Mammut Trion 38 Backpack: Features, Performance & Opinions

The Mammut Trion 38 backpack is versatile 4 season backpack suitable for summer backpacking trip, winter mountaineering trips, ice climbing and backcountry skiing. If you are looking for a backpack that can perform well in any of these adventures the Mammut Trion 38 deserves a look especially at a sub $200 MRSP!

Let’s start with the manufacturer description and then get into some details and opinions!

Manufacturer Description

The ideal partner for climbing, ski tours, and mountaineering, this versatile pack serves up lightweight comfort and exceptional durability for year-round alpine pursuits. Water-repellent and abrasion-resistant, our full Trion line was developed with pro alpinists Stephan Siegrist and Nico Hojac to optimize every last detail. Made of primarily recycled materials, the Trion 38 offers a host of practical features, including ice axe attachments, quick side access to the main compartment, and a designated avalanche equipment compartment. Complete with contact back system for optimal load transfer, you can stay fully focused on the next move ahead.

Suggested Activities

According to Mammut this pack was designed with these activities in mind. While I like this graphic visual I think it misses “ice climbing” and “cragging” as great uses for this pack, and I’m not even sure what one looks for in a Via Ferrata pack?

Features

  • Rolltop closure with zipper
  • Two ice axe attachments
  • Zippered side access to main compartment
  • Compartment for avalanche equipment
  • Elasticated chest strap for optimum comfort and a perfect fit
  • Large mesh pockets on the shoulder strap
  • Reinforced side ski attachment
  • Trekking pole carrier
  • Hydration system-compatible
  • Rope attachment on flap
  • Compression straps can be tensioned at side and front
  • Comfortable thanks to the anatomically shaped, soft padded hip belt and shoulder straps
  • Robust, abrasion-proof outer material
  • Flap with external and internal pockets with key pocket
Mammut Trion 38 Backpack Review

How I Tested

I tested this pack from mid-March 2024 to June 2024 while leading winter hiking trips above tree line in the White Mountains, teaching avalanche courses, and sneaking in some late season waterfall ice climbing in Dixville Notch. I’ve also taken it one some Spring hiking and climbing trips with loads up to 30 pounds.

Performance & Opinions

On the first day of use I appreciated the roll top with stiffener zippered closure for the main top access. This type of access allows you to really open the top of the pack up to make loading it with a gear quick and easy. With 38 liters (2,400 cubic inches) of space the pack easily swallowed my extra clothes, a 60 meter climbing rope, a full traditional climbing rack, and everything else one needs for a day of adventuring. My 70 ounce hydration bladder slid smoothly into the internal mesh sleeve and the one side zipper access point let me dig out my first aid kit to grab a blister bandage when my hiking partner developed a bit of a hot spot.

While priced closer to a general backpacking pack the Mammut Trion 38 has all the features of high end mountaineering packs. Things like dual ice axe loops that also have the elastic T-shaped pieces to accomodate any type of waterfall or general mountaineering ice axes. Side compression straps that can allow you to securely carry your backcountry skis in an “A-frame” style carry. A large removable top lid with both internal and external pockets.

Mammut Trion 38 Backpack Review

For comfort the Mammut Trion 38 has a “Motion V Frame” back panel that is lightly padded, breathable, and very form fitting. Unique to a pack this size, in my experience, are the running vest style shoulder straps. I appreciated how wide and distributive the shoulder straps are once I got them properly adjusted and loved the convenience of carrying my iPhone 13 ProMax in the stretchy shoulder strap pockets that I think are more often used by trail runners to carry small bottles of water or energy gels.

Summary

Overall I was impressed with the features, design, and quality of a backpack of this size that retails for less the $200. My only negative was I dislike all black backpacks, but fortunately this pack comes in a nice high visible orange and the brand recognizable white & black. It feels quite spacious at 38 liters and I think there is more then enough carrying capacity for 3-4 day backpacking trips. If you are in the market for a solid all around backpack that can handle a pretty wide array of adventures take a close look at this one. Mammut also has an outstanding warranty and repair program should your pack ever need some TLC!

Munter Mule Overhand (MMO): A Releasable-Under-Tension Knot

Munter Mule Overhand Climbing Knots

The Munter Mule Overhand or “MMO” is a combination of three knots that creates a releasable-under-tension method of securing a rope or cordelette. The MMO is useful in improvised self-rescue applications most often involving load transfers. In this situation I was using it to secure one end of a typical top-rope setup so my guest could practice rope ascension on the other end of the top-rope. The context here is if the climber practicing rope ascension gets a device jammed or has trouble transitioning from ascension back to descending I can remove the overhand, carefully deconstruct the Mule, then use the Munter to lower the climber back down to the ground.

Testing the Petzl Neox: Efficiency in Hauling & Ascension Systems

I’ve now had the Petzl Neox for about two weeks and have been able to form some opinions and test it in applications I’m most interested in. The most recent day I spent at the cliff with it was focused on seeing how it performed as a progress capture in an improvised hauling system and in a rope ascension system. Both these uses are important to me for assisting a seconding climber or rescuing an injured lead climber, and places where I would traditionally be using a Petzl GriGri. Here is some raw footage of this round of testing and some of my thoughts.

I assumed the Petzl Neox would work great for progress capture in this systems due to the spinning internal cog wheel and it definitely felt efficient in both the hauling scenario and the rope climbing scenario. I will be doing another round of comparisons with a more realistic full body weight load on the system but the fact the wheel still spun in my rope ascension test leads me to think it will still spin with a full load in a hauling system. This took me a little while to wrap my head around because you can seen when the device sees a full load while single strand rappelling the cam rotates, the wheel stops spinning, and you control your descent with the friction of the rope moving through the created bend. Why wouldn’t the wheel rotate and lock like that while using it as a progress capture?

The answer comes down to physics and while not having anything close to a degree in physics I can see how the device isn’t getting the full load in these scenarios. The full load is on the “tractor”, or friction hitch, or the Petzl Tibloc. When you go to pull slack through the Petzl Neox at that part of the cycle there is almost no weight on the device so the cam does not engage and the wheel spins freely reducing effort in hauling and ascending. When you relax during the hauling process all the load goes back to the Petzl Neox and the cam engages. Same with ascending, when you transfer your weight from your foot loop back to your harness the necessary threshold is exceeded and the cam engages. When you put your weight into your foot loop to progress the weight comes off the device and it is easier to pull the slack through the device then the Petzl GriGri.

Summary

It is still early in our broader exposure to this new belay device but the videos have been pouring out from influencers, highly certified guides, and rock star YouTuber’s. My opinion will likely evolve over the course of the summer as I put more days on the device, and expose more beginner climbers to it. For now I will re-iterate that I really like how easy it is to pull slack while belaying from above, and the more I think about it I do think this device may be in someways safer for a newer belayer as the instructions basically encourage you to not tough the device while paying out slack. This device may help prevent the holding open of the cam at risky moments which was likely part of the motivation of the anti-panic feature that came with the Petzl GriGri+.

Petzl Neox Assisted Blocking Belay Device: Initial Look

Today I was able to get out to the cliff for a short bit to check out the newly released assisted blocking belay device, the Petzl Neox.

This is not a full in-depth review. It is a preliminary look at this new option in assisted blocking belay devices and I try to distinguish some of the obvious differences in the Petzl Neox, the Petzl GriGri, and the Petzl GriGri+. As time allows I will be diving more deeply into the topics I mention in the video.

The Munter Hitch: History, Formation, and Applications

The Munter Hitch is one of the most valuable knots used in climbing and every climber should become familiar with this versatile hitch. While Werner Munter didn’t invent the hitch, a few Italian’s did in the 1950s, he was the one who popularized it in the 1970s and why it bears his name. This hitch works best on a large pear shaped locking HMS style carabiner like a Petzl Attach or Petzl William Screwlock Carabiner. Fun fact, the “HMS” is a German abbreviated for “Halbmastwurfsicherung” which translated means roughly “half a clove hitch” which describes the structure of this hitch. You can read more on this history of the hitch here.

  • Formation

To tie the Munter Hitch you form a twist in the rope similar to the Clove Hitch and drop a strand into the carabiner as well. It is really easy when learning this hitch to remove the twist when you add the second strand which leaves you with the rope just double looped through the carabiner which should be obviously incorrect. Watching a few videos of how to tie it along with plenty of practice tying it inside your home or on the ground should proceed you tying it for real life application.

One of the cool aspects of the Munter Hitch is that it is “reversible”, meaning it will flip through the carabiner into a different orientation depending on which strand is being loaded. During instruction we use the terms “load” strand and “brake” strand. If you only apply load to the “load” strand the hitch will end up in what is referred to as the “lowering” orientation. If we only apply load, or more commonly pull in slack while belaying, the hitch will flip through the carabiner into what is referred to as “belay” orientation. Generally when creating the Munter Hitch it is common to create an “air” hitch like demonstrated in the above video and then install it onto the carabiner. With a little practice it becomes efficient to tie the hitch directly onto the carabiner.

  • Advanced Formation

For those with a strong grasp on the basic ways to form the hitch it can be useful to learn how to tie the hitch onto the carabiner in the orientation it will first be operated. For example tying it so it is already in belay orientation, or tying it is it is already in lowering orientation. These methods can add efficiency especially when progressing to advanced self-rescue skills and for those seeking out guiding certifications in rock and alpine guiding.

  • Application
  • Belaying– The most common use for the Munter Hitch is an alternative to a plaquette style belay device like a Petzl Reverso or Black Diamond ATC Guide when belaying a second directly from the anchor. This choice may be because of a dropped belay device, or it may be for speed and efficiency, or it may be out of necessity (ice’d up frozen ropes while ice climbing can work better in this hitch and be near impossible to install into a plaquette).
  • Lowering– The smoothest way to lower a climber directly from above is by using a Munter Hitch and lowering directly from an anchor. A common misconception is this method will twist your rope up and/or greatly wear your rope as the hitch rubs on itself. Both of these conceptions are false with proper use of the hitch, which primarily means keeping the orientation of the BRAKE strand PARALLEL to the LOAD strand while lowering. Doing so will prevent any twisting of rope. The second consideration is conducting a smooth, steady, non-high speed lower. This will not damage the rope and modern rope have sheaths that can easily handle the minimal wear using this hitch hundreds of times will put on your rope. It is a good practice to use a “third hand” friction hitch on the brake side of the hitch connected to your belay loop while conducting anything but the shortest and simplest of lowers.
  • Rappelling– While it is possible to rappel short distances with the Munter Hitch attached to a locking carabiner on your belay loop it is a bit awkward to do so and the dramatic difference in angle that the two strands leave the hitch leads to massive rope twisting (and where this hitch probably got a misguided bad-wrap). In truth if you rappel by holding your brake strand parallel to the rope you can manage this without twisting your rope but this practice is very unintuitive to other modes of rappelling and I would only use it as a last resort.

Summary

The Munter Hitch should be in your top five familiar climbing knots. From belaying to lowering it has a lot of applications in climbing, especially in the self-rescue world when we start looking at tension releasable solutions (coming soon). If you haven’t used this hitch in your climbing take sometime to build it at home and see how it operates. Even with all the advanced and great belay devices on the market it is wise to have a fall back plan that only requires a single locking carabiner.

Free Range Equipment Canvas Packs: A Visual Delight for Climbers and Commuters

Earlier this year I received a sweet duffle bag and backpack from Free Range Equipment. This small brother & sister company with its roots in the Cascades has partnered with two dozen artists to create an assortment of visually stunning canvas packs. I received the Picket Range Duffel with art by Nikki Frumkin and the Dusk at Shuksan Pack with art by Gianna Andrews. I selected these two packs as I climbed Shuksan in 2017 as my first Cascade summit and during that same trip climbed Rainier and Forbidden Peak which isn’t too far from the Picket Range. I’ve wanted to get back to the Cascades for another climbing trip and the artwork on both these will keep reminding me I need to make a return trip soon!

Free Range Equipment Packs Review

I don’t usually review non-technical packs and these are designed more for travel and day-to-day type use, but I feel I’ve used them enough to share some opinions on them. The craftmanship of both is easily apparent even to the untrained eye. The canvas is thick and rugged, the zippers and stitch work are obviously high quality. The duffle is listed as 55 liters which makes it useful for for everything from a crag bag to regular travel luggage. A concealed backpack system is so concealed I didn’t even realize it was there until my second trip with the pack!

The smaller backpack is listed at 25 liters. It’s a perfect size for a gym or commuter bag and can easily hold my harness, climbing shoes, laptop, water and snacks for a trip to the local park, coffee shop, or climbing gym! It’s got a nice sized internal mesh pocket, a top pocket, etc, but there isn’t to much more for me to comment on with these packs, other than they are eye catching in the best way. I admit I’ve never been artistically talented but I love the style of both these artists and if you take a minute to look through all the offerings on the Free Range website you’ll likely find something that catches your eye.

Preventing Rappelling Accidents: How to Safely Use Girth Hitched Rappel Rings

On April 28th, 2024 a climber fell almost 400 feet sustaining serious injuries when their rappel system failed. The suspected mechanism of failure was an improperly threaded girth hitched rappel ring. In this video I demonstrate how this occurrence is possible.

Some key take home points;

  • For better and/or worse we are seeing girth hitched rappel rings on fixed rappel anchors
  • Careful inspection of the hitch and proper placement of your threaded rope is CRITICAL
  • Best practice is to ALWAYS stress test your rappel connection BEFORE you remove your lanyard from the anchor.

    Alpine Savvy also has a nice post with more information and some opinions on this situation here.

    Mastering the Clove Hitch: Essential Knot Tying Techniques

    The Clove Hitch is the most common knot used to secure oneself to an anchor and in this video I share the multiple ways I have learned to tie this excellent hitch.

    The first method I learned was to create the two asymmetrical loops and then “slide” the loops in front or behind each other. Then I learned the “crossed” hands method which takes a little practice but once you get it dialed it is a very fast way to form the hitch. The one-handed clove hitch is a bit of a party trick but still fun to learn. Finally learning to tie the clove hitch directly onto a carabiner with one hand is a worthwhile skill to master as you can increase your security on a small stance by holding onto the anchor with your off hand. I use this method most often while ice climbing but it’s useful in any climbing context.

    One tip to assist learning how to tie the clove onto a carabiner is to just start with a clove hitch already on the carabiner, and then slowly “deconstruct” the hitch only strand at a time. Then build the hitch again, and deconstruct again, and repeat until the muscle memory is gained!

    While you can also tie a clove hitch around a solid object, like a tree, I’ve never found a practical use for that method in the climbing world, so I do not demonstrate it here.

    How do you like to tie your clove hitch? Know any other methods that I haven’t listed here?

    Optimized Figure Eight Knot: Essential Steps for Tying

    The first knot most climbers learn is the “Retraced Figure Eight” knot. While a minority of climbers choose to connect the rope to their harness with a double bowline knot most of the climbing guides and instructors I have met greatly prefer to the more easily recognizable Figure Eight. Since there are a few ways to create a retraced Figure of Eight there is only one way that is becoming more known as “ideal”. When all these points are met I refer to this as the “Optimized” Figure Eight Knot.

    • Only the amount of rope needed to create the knot is used
    • The loop that has captured the harness tie-in point is no larger then the belay loop
    • All the strands are parallel with no cross overs
    • After all four strands exiting the knot are “dressed & stressed” there is only 6 inches of tail
    • The load strand entering the knot ends up on the “inside” of the knot
    • Your partner checks your knot before you start climbing

    In this video I demonstrate the methods I use to tie this correctly each time.

    There is a really in-depth look at this by “Hard is Easy” on YouTube here, though I use a mirror image of his method to achieve the same result. There are also some great pictures showing some of the nuances over at Alpine Savvy.

      Tech Tip: Extending From Your Anchor For Better Communicaton

      Rock Climbing Tech Tips
      “The Fairy Tale Traverse”, Northeast Ridge of the Pinnacle, Huntington Ravine, Mount Washington. Photo by Peter Brandon

      Oftentimes we have anchors that are set back from the cliff edge. If we belay at these anchors communication can be hampered. In this video I demonstrate some of the methods you can use to extend yourself back to a position to improve communication (and provide better photo opportunities!).

      A question from a follower last week asked “Can I just estimate the length, clove in, and leave my belay device up at the anchor?”. While that could work, it is generally a better practice to keep your belay device within arms reach. In the event you need to lower your partner, or build a 3:1 haul system to help them, it is more easily handled when the belay device is still within reach.

      Another great way to improve communication is to climb with a pair of Rocky Talkies! These radios are incredibly rugged, lightweight, and are so much better to use than straining your vocal cords yelling “off belay” from 50 meters away.
