Gear Review: AKU Hayatsuki GTX Mountaineering Boots

AKU Hayatsuki Mountaineering Boots Review

I’ve had a few months to demo and review the Italian made AKU Hayatsuki Mountaineering Boots and I’m ready to share my opinion on them! Let’s get the disclaimer out of the way first. I first heard of this company through a social media ad and I purchased a pair of the AKU Rock DFS Approach Shoes because I have a thing for approach shoes! The shoes performed so well I published this review and later reached out to see if I could get a media sample of the AKU Hayatsuki Mountaineering Boots to review. AKU supplied me with a pair to check out but this has in no way effected my opinion of the boots. Read on to see how they were tested and how they performed!

AKU Hayatsuki Mountaineering Boots Review

How they were tested:

Test period: December – March

Use: Winter hiking, mountaineering, and waterfall ice climbing in the White Mountains of New Hampshire. Approx. 20 days of use, 100+ miles, over 40,000 feet of elevation gain/loss.

Bottom Line (TL;DR version)

These are a solid choice for the winter hiker/climber who spends equal time between general winter mountaineering (snow climbing) and more technical waterfall ice climbing that won’t break the bank!

The Details:

Sizing/Fit/Comfort:

I went with a UK 8, EUR 42, USA M 8.5 and the fit was perfect for my medium width foot with a regular arch and a slight Morton’s toe. The lacing system has a great pulley system at the lower top of the foot, 6 “mini” pulley’s to be exact then a self-locking ratchet mechanism. This system makes securing the foot in the boot super quick and efficient. The result is zero toe-bashing while kicking up waterfall ice while wearing crampons or while descending of any steep hiking trail. I never felt a need to “snug up” my laces for the descent with these boots feeling comfortable and secure all day long!

Performance:

For general winter hiking and mountaineering these performed quite well! AKU doesn’t list how much Primaloft insulation is in the liner but there is enough to keep my feet toasty down to 10 degrees below Fahrenheit with wind chills around -20 to -30 above tree-line. My feet stayed warm throughout each trip (wearing my Darn Tough Mountaineering Socks)! For general winter hiking and mountaineering I paired them with my Petzl Vasak 12-Point Mountaineering Crampons and they worked great together!

For ice climbing I was quite impressed with their performance, especially at the price point! The lasting board, which gives the sole its stiffness, is made out of “6-4 MM Nylon & Die Cut EVA for Rock Protection & Stability”. More important to me is the welt is fully compatible with my technical ice climbing crampons with a solid front and back lip on the welt. My Petzl Dart Crampons fit perfectly on the welt and felt secure on many pitches of Grade 3 waterfall ice.

AKU Hayatsuki Mountaineering Boots Review

Summary

The AKU Hayatsuki Mountaineering Boots are a great winter “all-a-rounder” that will basically perform well in pretty much any snowy situation below 8000 feet. This makes them an excellent choice for winter hikers working on their “Winter 48” 4000 footer list, and for winter hikers who are considering breaking into the waterfall ice climbing sport. They are technical enough to handle waterfall ice and mixed climbing at almost half the price of most technical ice climbing specific boots. The fact that they are made in Italy is apparent in their craftsmanship and I have no doubt these boots can survive a decade of winter exploration. If you’re in the market for a great pair of winter hiking boots you should give these a try!

Making a Case for Avalanche Airbags in the East

In almost every avalanche course I teach we have a discussion about the use of avalanche airbags. My opinions on this matter have changed over time in light of new information and advancements in technology. Earlier in my avalanche education days I would cite statistics such as 75% of avalanche fatalities on Mount Washington were caused by trauma, not asphyxiation, the mechanism of death that an avalanche air bag is supposed to reduce the chance of in certain situations. Therefore I would conclude, perhaps wrongly, that avalanche airbags did not seem as valuable in our unforgiving terrain. In this article I will present a new argument for the use of avalanche airbags in the East, specifically for the backcountry touring community. First, a bit of background information that may be useful to the uninitiated.

How They Work

Simply put an avalanche airbag backpack has a handle or “trigger” that gets pulled by the wearer when caught in an avalanche which then causes a deployment system, either compressed air or electronic, rapidly fill a large rugged “ballon” that was stored inside the backpack. This “ballon” basically works to keep the wearer closer to the surface of the snow in a moving avalanche via “granular convection“, often referred to as the “Brazilian nut effect”. This video shows the effectiveness quite well.

Here are a few other things I will note that are relevant to this video. First, backcountry snowboarders and split-boards should see the value in an avalanche airbag perhaps at a higher level than skiers. The reason for that is these travelers do not have release-able bindings and therefore are more likely to be pulled under the snow during the type of avalanche motion seen in this video, referred to as “wet flowing” in the snow science community. Second, this avalanche path is a good example of a path with a safe runout. An avalanche airbag deployment is less likely to result in a positive outcome if you have terrain traps below you i.e. rocks, trees, cliffs, gullies, crevasses, creeks, etc.

A Change in Demographic

Before 2019 the main demographic for avalanche fatalities on Mount Washington were either ice climbers or winter hikers (11) and only three skiers. There has been an obvious shift in how people are recreating in the terrain with a noticeable explosion of the backcountry touring population (AT skiers, Split-boarders, Tele). This change in usage increases the chance of a survivable avalanche in a few ways.

First, getting caught in an avalanche while on foot or while skinning low in an avalanche path is often more serious than triggering something from the top. While there’s obviously a fair amount of luck surviving any avalanche the first avalanche involvement of our season resulted in no injuries for the person who triggered the avalanche and was carried the full slide length while the victim who was hit mid-path suffered serious trauma. In January of 2016 while teaching an avalanche course in Tuckerman Ravine I watched 4 people get caught and carried in an avalanche right next to our class. The avalanche also hit a 5th person in the runout resulting in the most serious injuries of the incident. Last year’s well reported Wilson Glade quadruple fatality (Utah) also showed how getting caught in the up track while ascending can have more dire outcomes.

Second, while it is suggested that anyone recreating in avalanche terrain carry the appropriate safety gear (transceiver, probe, shovel, and perhaps an avalanche airbag) this author believes these items are still less likely to be carried by the eastern ice climber or mountaineer. The merits and justifications of this choice are for another topic but I will suggest the fact that the majority of backcountry touring parties are carrying basic avalanche safety gear this user group is more likely to survive an encounter with an avalanche than a group without these items.

A Increase in Acceptable Risk

In a recent survey of backcountry touring groups who travel in avalanche terrain I asked two questions. The first:

While not unexpected the majority responded they would consider touring in avalanche terrain under a “Moderate” danger level. The North American Avalanche Danger Scale describes the likelihood of a human triggered avalanche as “possible” under a Moderate level, and “likely”, under a Considerable level. Almost one in three respondents would consider traveling in avalanche terrain when both natural avalanches are “possible” and human triggered are “likely”.

While some research has shown that the most avalanche fatalities occur during a “Considerable” danger level:

Graph courtesy of Colorado Information Center

Other research shows that “Moderate” is actually the danger level where most fatalities occur:

Avalanche Airbags in the East
Graph courtesy of Colorado Avalanche Information Center

Since these stats can be adjusted based on what data sets you are looking at I will just look at the fatalities and involvements I have personal experience with.

avalanche mount washington
The author buried to his waist in an avalanche in Oakes Gulf wondering why he wasn’t wearing his avalanche airbag on this Moderate level day, April 2019

At least four of the last 6 fatalities on Mount Washington occurred under a “Moderate” danger level. The majority of reported “near misses” and involvements occur under a “Moderate” danger level. As a region we also see a fair share of incidents when under a “General Advisory” early in the season before the Mount Washington Avalanche Center starts issued daily forecasts.

The second question I asked in the recent survey was:

Avalanche Airbags in the East

These results confirmed my suspicion that avalanche airbag usage in the East is still an exception and not common place. Based on the change in demographics, risk acceptance, and improvements in technology I believe we should see this change.

Improvements in Technology

Probably the biggest change an avalanche airbag technology is the growing availability, lower costs, and convenience of electronic airbag systems. Traditionally canister style avalanche airbags were the most common. Having to maintain a canister type system is likely a deterrent for many who might otherwise benefit from owning an avalanche airbag. Air travel with canister systems can be difficult, requiring you to discharge the system and find someplace at your destination that can refill your canister. You’d be less likely to practice deploying your airbag if the system only allowed one deployment. Now there are multiple electronic models that allow for multiple deployments, are easy to fly with, and can be charged anywhere you have an electric outlet. Some notable electronic models now available:

Pieps Jetforce BT Booster 25L Avalanche Airbag Backpack SALE

Pieps Jetforce BT Booster 35L Avalanche Airbag Backpack SALE

Osprey Packs Sopris Pro Avy 30L Airbag Backpack- Women’s

The Paradigm Shift

The real reason for my change in opinion on the validity of avalanche airbags in the East is a bit personal. When looking at the last two avalanche fatalities on Mount Washington the case for more common airbag usage is clear to me. There is a very important similarity between the tragic deaths of Nicholas Benedix in 2019 and Ian Forgays in 2021. Both of these backcountry riders were caught and carried in their avalanches, likely with the “wet flowing” motion shown in the previous video, and both ended up buried under the snow without suffering any trauma. Certainly a nearby partner who was not caught in the avalanche and had the right rescue gear and training may have been able to make the “save”, but unfortunately both were alone and unwitnessed avalanches. Take home point for me here is riders who occasionally travel solo in avalanche terrain should certainly consider the added layer of protection an avalanche airbag might provide. On the same day as Nicholas’s avalanche I myself triggered a large avalanche a few drainages away and was lucky to only be buried up to my waist. One of my only thoughts as I saw the snow coming down from above me was I was not wearing my avalanche airbag. Even more recently was a miraculous save in the Adirondacks just a week ago after two skiers were caught, one fully buried and the other just enough to still get out and save his partner. They were the only two in the area and if but a few more inches of snow this would have been a double fatality.

Summary

Research shows avalanche airbags save lives, suggesting a deployed avalanche airbag will reduce mortality by 50% . While they should not be considered 100% protection against getting hurt or killed in an avalanche wearing one in avalanche terrain adds another layer of protection from the hazard. While the increase in backcountry travelers wearing avalanche transceivers has noticeably increased in the last 10 years I expect to see an increase in avalanche airbag use in the east over the next ten years, and for good reason. We just recently had our first avalanche transceiver full burial save in the eastern US, and I believe the first avalanche airbag save might not be that far in the future.

Tech Tip- Reduce Effort While Using a Plaquette Style Belay Device

When using a plaquette style belay device (Black Diamond ATC Guide, Petzl Reverso, DMM Pivot) in Assisted-Braking Mode or Auto-Blocking Mode (to belay a follower directly off the anchor) there are some ways to reduce the amount of effort required to pull slack through the device. This can lead to a more efficient belay as well as save your elbows from over-use injuries like tendinitis (not uncommon in life long climbers and guides).

First make sure you are using an appropriate diameter rope for your device. Skinnier ropes will require less effort to pull slack then thicker diameters but make sure you are staying within the range the manufacture recommends! For reference here are the suggested ranges for some common devices:

Black Diamond Alpine ATC Guide (8.5mm – 9mm single ropes)

Black Diamond ATC Guide (8.9mm – 11mm single ropes)

Petzl Reverso (8.5mm – 10.5mm single ropes)

DMM Pivot (8.7mm – 11mm single ropes)

The skinnier rope you use the less effort it will take to pull slack through the device. Currently my favorite single rope for multi-pitch ice and alpine rock climbing is the Sterling Fusion Nano IX DryXP, 70m. This rope pulls very smoothly through any of the above devices!

Next be sure to use a round stock locking carabiner like the Black Diamond RockLock Screwgate Carabiner for the rope to run around as opposed to a forged carabiner with “ribs”. The rope will pull noticeable smoother around a round stock carabiner.

Climbing Tech Tips
A round stock carabiner makes pulling slack through the device easier than a forged carabiner with “ribs”

Finally consider adding a second carabiner for the rope to run around. This will again reduce the effort of pulling slack through the device with out removing the assisted-braking function.

Two carabiners greatly reduces the amount of effort required to pull slack through the device

I hope this tech tech helps your belays run more smoothly! Your elbows will thank you!

Tech Tip: Buntline Hitch

rock climbing tech tip Buntline Hitch

There are many situations in climbing where it makes sense to construct your anchor from the climbing rope you are already attached to versus reaching for a sling or cordelette; most notably when swinging leads or finishing a climb with a tree anchor followed by a walk-off. In recent years the Connecticut Tree Hitch (CTH) has gained popularity among both professional climbing guides and savvy recreational climbers.

The Buntline Hitch is also a suitable option that has a few distinct advantages over the CTH.

  1. The hitch does not require a locking carabiner
  2. The hitch forms a suitable master point for belaying your second (when using a CTH you must tie another bight knot to create a master point).
  3. If tied incorrectly it forms either two half-hitches or a clove-hitch which have a high enough slip strength. The CTH tied incorrectly will catastrophically fail.
  4. It is fast to tie and untie

Credit: Big thanks to Derek DeBruin for sharing this hitch with in the AMGA Professional Facebook Forum and for his continued work disseminating quality information. EDIT: Derek credits Richard Goldstone for teaching him this method.

Tech Tip: Rappel/Rigging Rings as Master Points

With the gaining popularity of the Girth Hitch Master Point Anchor option I am making the case for using a closed rappel or “rigging” ring as the master point instead of the commonly used locking carabiner. Some advantages of this choice;

  1. A closed rigging ring can’t be accidentally opened or left unlocked.
  2. Using a rigging ring means you save a locking carabiner in the anchor construction
  3. Adding a rigging ring to your regular kit means you will have one to leave behind should bailing be necessary (they are all cheaper than most locking carabiners)
  4. A rigging ring is “omnidirectional” so you do not need to worry about optimum loading, short axis loading, gate loading, etc.
  5. In most cases a rigging ring is lighter than a locking carabiner

Disadvantages of carrying and using a rigging ring in your kit are almost non-existent. One of the challenges is deciding which rigging ring works best for recreational/guiding in this system. To assist with that I purchased 5 of the more common rappel rings and will share the specifications and considerations for each to help you decide! Let’s start with this weight/strength/price comparison… I added a Petzl Attache Carabiner for comparison reasons.

FIXE Stainless Steel Ring86 grams35kN34mm$5.95
Petzl Attache Carabiner58 grams22/8/6 kNn/a$15.95

Now let us take a closer look at each option from lightest to heaviest and how practical each is for this application starting with…

ModelWeightStrength RatingInteral DiameterCost
SMC Aluminum Descending Ring12 grams14kN38mm$3.75
Girth Hitch Master Point Rappel Ring Anchor

The lightest and cheapest option is by far a SMC Aluminum Descending Ring. While ultra-light weight I am slightly concerned about the lower strength rating compared to other options. 14kN is over 3,000 lbs, which is a much higher force than the master point of your anchor should ever see. In a response to a REI slack online customer asking about the strength of these SMC stated “If you over tension the slack line you may notice some flex as the units start to elongate around 800 lbs”. So while these are strong “enough” for use as a master point I’d prefer something rated higher so I’m not second guessing myself while setting up a haul system or the dreaded “fall factor 2” type scenario (should never happen!). They are super cheap and light though, and easily fit three or four locking carabiners.

ModelWeightStrength RatingInteral DiameterCost
SMC Rigging Ring26 grams32kN28mm$5.95
Girth Hitch Master Point Anchor System

At about double the weight and 2.5 times the strength the SMC Rigging Ring seems like it might be perfect for this application, and it is, for two piece anchors and two person climbing parties. The issue with this ring is once you have a three-piece girth-hitch anchor internal space in the ring is a bit on the tight side to fit three locking carabiners (party of two) and impossible to fit four locking carabiners (party of three, guiding). Here’s a shot of this with a three piece anchor and you can see how tight it is.

It works but I don’t like how the carabiners bind on each other in this situation. So this would only be a good choice for two piece anchors and two person parties. Next up…

ModelWeightStrength RatingInteral DiameterCost
RNA Revolution Ring, Small38 grams25kN30mm$5.99
Girth Hitch Master Point Anchor System

A little more weight (38 grams) and a little less strength (25kN) with just 2mm more internal diameter the RNA Revolution Ring, Small works great on this three piece two person anchor. If you don’t often climb in a party of three this is a good choice. This brings us to what is becoming my favorite option…

ModelWeightStrength RatingInteral DiameterCost
RNA Revolution Ring, Large56 grams25kN40mm$6.99
Girth Hitch Master Point Anchor System

The RNA Revolution Ring, Large is my best in class for this comparison. While it weighs close to a Petzl Attache Locking Carabiner (56 grams vs Petzl Attache 58 grams) it still has a few advantages as a master point. It has plenty of space for more than 4 locking carabiners so this would be great for recreational and guided parties of 3+. It’s stronger in all directions than most aluminum locking carabiners (25 kN). It can easily accommodate a three or four piece girth hitch, and is easier to handle with gloves on (ice climbing FTW). We will finish with a quick look at the heaviest option…

ModelWeightStrength RatingInteral DiameterCost
FIXE Stainless Steel Ring86 grams35kN34mm$5.95
Girth Hitch Master Point Anchor System
Girth Hitch Master Point Anchor SystemGirth Hitch Master Point Anchor System

If you are not very concerned with weight the FIXE Stainless Steel Ring is a beast carrying a 35 kN rating with its 86 grams of weight. It can easily handle three lockers on a three piece anchor but a fourth locker would be pretty tight leaving this an option for two person parties.

Summary

Using a rigging ring is common in high angle rescue and industrial work and with the growing use of the Girth Hitch Master Point Anchor method recreational climbers and guides should consider the use of closed rings to create their master points for the advantages stated at the beginning of this post. No one anchor solution is appropriate for all situations and you should certainly practice this on the ground and seek qualified instruction and mentorship before trusting your life to any advice in this post. That said I think this method works quite well when appropriate and I expect it will be one of my common builds when multi-pitch climbing whether it be rock or ice (though I think this will really shine this winter while ice climbing).

Discount Purchase

After purchasing and testing these rings I let Rock N Rescue know their RNA Revolution Ring, Large was my “best in class” for this purpose and then they offered my readers a 10% discount on any purchases from their website with coupon code “AlpineStart10“. If you decide to add one of these to your kits you can save a little money on the purchase and at they the same time support the content I create here (this discount code will also earn me 10% of the purchase).

Tech Tip: Girth Hitch Master Point Anchor System

Girth Hitch Master Point Anchor System

I’ve been using the Girth Hitch Master Point (GHMP) Anchor System for a little over a year now having learned it from the great educational social media feeds of Dale Remsberg and Cody Bradford. Recent testing on the method was conducted by Derek DeBruin and John Sohl the Petzl facility in Salt Lake City and they published these results.

TL:DR Version:

“The girth hitch is a viable solution for the master point for anchor rigging, provided that;

1) Approximately 5cm of slip is within the climbing party’s risk tolerance

2) The girth hitch is cinched snugly by hand and body weight prior to use. This applies to a variety of rigging materials, such as HMPE or nylon slings or cord, as well as material conditions, whether new or used, dry or wet.” – Derek DeBruin

Best Uses:

There’s quite a few places this system could be well applied. It is primarily a solution for multi-pitch climbing. This isn’t a great option for constructing anchors that will be used for top-rope climbing. On a multi-pitch route with bolted belay stations I might even consider keeping a sling rigged with this system (much like how I keep a pre-tied mini-quad on my harness). Even if the bolts at the next station are not exactly the same distance apart you only need to loosen the hitch a bit to properly adjust it. On a multi-pitch route with traditional gear anchors a double-length Dyneema sling is a light & fast option for rigging this system. Multi-pitch ice climbing is where I see perhaps the greatest benefit as rigging this with gloves on will often be achievable with just an alpine-draw and good ice.

Here’s a video I created showing the method along with some suggestions, namely utilizing a full strength closed rappel ring as a master point instead of a locking carabiner, which adds security and saves a locking carabiner for other uses.

Summary

Because this is a material efficient and proven redundant glove friendly system I plan on keeping it in my growing “tool kit” of options. I still carry one mini-quad with me when I prefer independent master points (more comfortable for a party of three) and use it often as a glove friendly redundant rappel extension. The advantages over tying a more traditional old school pre-equalized cordelette anchor are great enough that I see less and less reason for ever taking my cordelette off the back of my harness. I still carry it for self-rescue purposes but newer anchor methods like the GHMP and mini-quad seem to solve most anchor problems more effectively. I’m stopping by REI today to pick up one a SMC Rigging Ring which is almost half the weight of the stainless steel one I used in the video. You should consider adding this to your tool kit!

Tech Tip- Snap Bowline with Yosemite Finish

The bowline is an excellent knot for securing your climbing rope around an object, most commonly a tree. You might be securing the bottom of a stacked rope while top-roping to “close the system” while also creating a handy ground anchor if needed, or fixing a rope for a single strand rappel while scrubbing your next project. In this short video I demonstrate the traditional “scouts” way of tying it as well as the alternative “snap” method (I refer to this also as the “handshake” method). I also demonstrate an alternative way of finishing the knot with a Yosemite finish.

How I Tested

I used this jacket for about a dozen day trips this winter including summiting Mount Washington with wind chills around -30f to -40f, alpine ice climbing on Mount Willard with ambient air temps around 10f, top-rope guiding at Cathedral Ledge, and while standing in snow pits teaching avalanche courses in Tuckerman Ravine during mixed precipitation weather.

Performance

As I mentioned in the introduction the Arc’teryx IS Jacket is a FURNACE! This is thanks to the exclusive “Thermatek” syntheric insulation which has amazing heat retention properties while being so light and packable. From Acr’teryx:

Exclusive to Arc’teryx, ThermaTek™ is a continuous filament, synthetic insulation that is treated with DWR (Durable Water Repellent) to make it highly hydrophobic, which means that it repels moisture very efficiently. The lofty insulation is then laminated to a backing fabric to ensure an even distribution and insulation.

Key Advantages

  • Arc’teryx’s most efficient insulation when used in humid and wet conditions
  • Very resilient and durable
  • The fastest drying fill insulation in our collection

While I am not a fan of this color (it is also available in a much more visible “Magma” color), I found the black color to be even warmer if the belay stance was in the sun.

I also said this jacket is BOMBPROOF, both against all forms of precipitation and winds but also against abrasion. The weather protection comes from the N40p-X 2L GORE-TEX membrane. water-tight zippers, and DWR treatment. The abrasion resistance is thanks rugged shell fabric and fully taped seams.

Weight/Packability

Manufacturer listed weight is 610 grams, 1 pound and 5.5 ounces. My home scale weighed my size large sample with the storage sack at 680 grams, 1 pound and eight ounces. The jacket easily stuffed into the included stuff sack with measures about 10 x 6 x 6 inches and could be compressed further.

Sizing/Fit

Despite my measurements being a little closer to a medium I went with the large size so it would easily fit over my other layers including a light weight puffy. The sleeve length was perfect and I choose to wear this over my harness at belays. To be honest I don’t know how Will Gadd was leading steep ice while wearing this jacket… it’s too warm! The hood is generously sized enough to easily fit over my helmet.

Features

There are a lot of small design features I liked in this jacket. The elasticized cuffs easily kept snow out and warmth in. The large internal drop pocket kept my water warm and handy while hanging around ice cragging. The stiffened visor kept freezing rain off my face while explaining the Alpha angle to students in an avalanche class in Tuckerman Ravine. The “almost” waterproof chest pocket kept my iPhone protected during moderate rain over the Christmas vacation week. The hood easily fits comfortably over my climbing helmet.

Improvements

There isn’t much I would change with this piece. A softer piece of material in the “chin” area might be nice but most the time I was wearing this jacket with a buff on anyways. The shell and internal fabric is a bit on the “noisy” side, but that’s such a minor observation I don’t think anyone would notice unless you were trying to stalk a deer or something. And as mentioned, I’d like this more in the Magma color as I prefer high visibility colors for winter mountaineering and ice climbing!

Summary

The Arc’teryx IS Jacket is basically the brand’s highest end synthetic belay parka and hard shell jacket in one piece. With a high level of heat retention and protection from wind and rain this really is designed for harsh conditions. I would be hard pressed to find a synthetic puffy and hardshell combo and stay this far under two pounds! Granted the jacket commands I high retail price, but when you consider the price of a separate belay parka and hardshell of this quality I can start to see why it comes in where it does. If you climb in warmer, less harsh, conditions than our local Mount Washington, you might prefer to keep the “puffy” and hard shell as two separate pieces for more versatility, but if you are looking to simplify your clothing system for extreme cold or wet conditions this would be a piece worth looking at!
