This summer I received the Black Diamond Rock Blitz 15 backpack to review and I’ve since logged about 25 days of multi-pitch rock climbing and guiding and a half dozen hikes with it. Weighing less than a pound but able to carry my full summer guiding kit I found this to be a great multi-pitch climbing pack and only have a couple small tweaks I’d love to see Black Diamond make.
UPDATE: Contest over! Congrats to Chris B. and Forrest for identifying the climbs!
Let’s start with the manufacturer description:
A worthy addition to any multi-pitch kit, the Rock Blitz 15 is designed to move with you pitch after pitch, carrying all the essentials to the summit. Featuring our signature Blitz-style main opening and a side zip pocket for quick on-route access to a phone, topo, or camera, this pack also has a stripped-down profile for moving fast on big lines. The top closure strap doubles as a rope carry once you summit, and external H2O hose routing gives you the option of staying hydrated on the send. The pack’s EVA padded shoulder straps and back panel make for all-day comfort, while the sternum strap and waist belt are fully removable to save weight on fast and light pushes.

External side zip pocket for quick access to guide book / phone / camera
Stripped down pack silhouette for moving fast on multi-pitch missions
Top strap also doubles as rope carry
External H2O hose routing
EVA Padded shoulder straps and back panel
Height adjustable waist belt for better fit above a climbing harness
Fully removable sternum strap and waist belt to shave weight when necessary
Volume : 15 L (915.4 cu in)
Average Stock Weight : 403 g (14.2 oz)
Materials : 840 D Nylon
The Black Diamond Rock Blitz 15 only comes in one size. Like most climbing packs designed to be worn while leading multiple-pitch rock it rides high on my 5’9″ build, 16 inch torso. The thin waist belt easily rides above my harness and helps secure the pack from swinging around when moving over terrain. The contoured EVA foam shoulder straps easily distribute the weight of a full kit. My only wish is the sternum strap used a more traditional slide adjust system vs the girth-hitched attachment points it currently uses and that the sternum strap buckle had the built in whistle that most climbing packs use these days.
For a simple pack there is some definite stand out features that made me really enjoy this pack. First off is the 15 liter volume. With careful packing I could fit a full guiding kit in here. For reference this is what I fit inside the pack:
This much gear was a snug fit and I’d either carry or just wear my Black Diamond Vapor helmet to the wall. The 840 denier ballistic nylon held up great to a full season of guiding. While I never hauled the bag up a pitch I did wear it through multiple squeeze chimney’s and the pack still looks quite new. The external side zip pocket is advertised to carry your phone, guidebook, or topo. I actually fit my first aid kit and my phone in it for easy access!
Here’s a quick look at the pack after finishing a day of climbing at Cathedral Ledge.
Black Diamond also produced a sweet little video showcasing this pack and a couple other products. I especially liked how they used the “guidebook/phone” pocket… skip to 1:58 to see the 11th “essential”…
This is a great little rugged multi-pitch backpack! Not a lot of thrills but simple and effective for what it was designed for! While it’s main end-use is multi-pitch trad climbing I found it great for quick trail hikes around the White Mountains and along the Maine seacoast. It was also quite useful on a family vacation when were walking around multiple seacoast towns. If you’re in the market for such a pack take a good look at this one!
For those who want a little extra room (and the option to carry ice axes) Black Diamond makes a 20 liter and 28 liter version!
Could you figure out what climbs the two “anchor” pics were? The first who answers either one correctly win a Black Diamond Pearbiner Screwgate Locking Carabiner. If the first person gets both right first they win both carabiners! Bonus cool points if you can also name what pitch I was on!

I’m up early but it looks like my guiding day might get rained out so I decided to scour the web for some of the better deals on outdoor gear and clothing as most companies end their Labor Day sales today. Below is a curated list of what is not only on sale but something I have personally owned and tested or is on my wish list!
REI is running some sweet deals like 20% off Thule and Yakima racks and roof boxes! 25-30% off most REI, Big Agnes, and Nemo tents and sleeping pads! They also made it easy to find the items that are actually 50% off by grouping them under their “Peak Deals“. Expect limited quantity and sizes in there!
Eastern Mountain Sports is going big with quite a bit of inventory 70% off! 20% off all Black Diamond, 20% off La Sportiva Footwear, and a current coupon for an extra 20% off a full or sale priced item! COUPON CODE: “LABORDAY19“. There is a fairly long list of excluded brands though… you can see the list here. Finally they have summer clearance items listed at 70% here!
Patagonia is running some great web specials like 40% off the Micro Puff and Nano Puff jackets and hoodies visible here.
Just about every retailer is running sales today and since it looks like a wash-out here in the Northeast I think I’ll spend some time today organizing my gear closet and seeing if I’m all set for the rapidly approaching Fall!
Coming soon… I’ve got reviews in the works for the new Wild Country Revo Belay Device. The “Take20Summer” coupon code does work on this item by the way! I also finally got my hands on both the Mammut Smart 2.0 and the Mammut Alpine Smart and testing has begun! Expecting to have reviews on all of these done in time for Rocktober!
Climbing trip to Camden ME in two weeks! I’ve been to Camden twice for some family camping but this trip it’s just me and my buddy Bob heading out to sample the climbing there. Have you been? Must do routes? Let me know in the comments below!

I’m going to skip listing the whole manufacturer description and non-relevant specs as those are easily seen on the companies website linked above. Instead I’ll focus on how I tested, first impressions, who I think this pack is perfect for, and some of the minutia both good and bad.
How I Tested
I’ve worn this pack for about 40 miles of hiking in the White Mountains between May-August. I took it rock climbing once, hiking 6 times, and casual road biking with the family twice. Most of the testing was during the hottest weeks of our summer where the allure of actual cold water on a trip outweighed some of slight negatives of my first impressions of the pack (more on that below). While temps were often in the upper 80’s New England’s famed humidity often had heat index’s reach into the upper 90’s.
Right out of the box I was a bit concerned with the empty pack weight. At 3.6 pounds (1633 grams) this is definitely on the far end of the spectrum for packs I consider for day trips. Once I convinced my ounce-counter-self that not every pack design needs to focus on shaving grams I started looking at what I would gain with carrying a pack that was comparatively heavy on the volume to weight scale. Let’s start by addressing the penultimate claim Hydro Flask makes regarding this pack… it keeps water COLD for 4+ hours!
How it Performs
Keeping Water Cold– That is where this pack truly shines. I’ve tried a lot of tactics over the last two decades to carry cold water in the mountains on long hot days. I used to freeze hydration bladders the night before a hike and then enjoy the long slow melt out during a hike (but it never melted fast enough and my spine pretty much had frostbite). I’ve filled reservoirs half way with ice which might buy me two hours of cold hydration on the hottest hikes (but this “sweats” a lot of condensation adding a fair amount of moisture to the contents of my pack).
This is where the “Revolutionary Cold Flow™” system comes in. It starts with a 3 liter HydraPak® insulated reservoir that is easily removed thanks to the Plug-N-Play™ connection system. A “fill to here with ice” line is about a third of the way up the reservoir. Once filled with ice and topped off with cold tap water this insulated reservoir slides into an insulated pocket on the back panel of the pack. Interestingly the connected hose is not insulated which isn’t a big deal. After a bit of hiking without sipping you’ll notice how cold the reservoir still is after an ounce or two of warmer water thats been in the tube. Finally the back panel of the suspension system is well ventilated to help keep body heat from reaching the reservoir. In practice I found the system could easily uphold the 4+ hours claim even in 80 degree temps.
Organization– For a mountain biking or hiking backpack I found the pack layout to be quite nice. There are two main compartments which feel to have the same volume when the bladder is full and in place. The outer pocket has some nice stretchy organization internal pockets. There is also a zippered top pocket that easily accommodates a first aid kit, lunch, headlamp, car keys, etc.
Comfort/Fit- I went with the M/L size for my 5’9″ build. The waist belt rides a little high as I’d expect for a pack designed with mountain biking in mind. The higher riding waist belt was also a benefit when used while wear a climbing harness. The contoured dense foam shoulder straps fit well. Most of the packs weight will be carried on the shoulders as the waist belt is pretty small. Not really an issue in a pack that is only intended for 15-20 pound loads. I found the pack to carry well while hiking and biking but I would chose the 10L version for a dedicated mountain-bike or trail running pack.
Who is this for? (Summary)
As I mentioned in my “first impressions” this pack is noticeably heavier than most of the packs I test. This weight is a necessary component of a hydration pack designed to be so well insulating. There really isn’t much on the market to compare this pack with for what it’s intention is. I see it as being more attractive for sports where an extra pound isn’t really a big deal (mountain biking, road biking, casual/family hiking, kayaking/canoeing, fishing). The luxury of cold water isn’t as important for sports where less is sometimes more (rock climbing, trail running, fast-hiking).
Made with waterproof zippers and fabric this pack would lend itself well to water sports, slot canyoneering, and wet climates. The lack of an insulated tube makes it a poor choice for winter sports and I’d keep this one in the gear room for the warmer months. It’s been perfect for a number of family hikes and a couple outdoor concerts at our local ski hill this summer.
All in all I’m happy to see Hydro Flask has entered this new market and think this first line of packs is a solid addition to their line. I’m also happy to see Hydro Flask still has a customer friendly warranty! If you put a premium on having cold drink stay cold for the longest possible time you should take a look at these packs!
Backcountry has both the 20L and 10L models in stock and is running a 20% off coupon! Details here!

Those who know me know I can be a little obsessive about gear. I enjoy making detailed gear lists for trips sometimes weighing everything down to the ounce. I shared my first gear list for ski touring in Iceland this past April and most recently in a trip report for climbing Mount Shuksan in the Cascades. I’ve decided to give the gear list its own post that can be easily linked too without taking up so much space in the trip reports located at these links:
A super lightweight and pack-able 2 person single wall tent. I spent 12 nights in this from car camping between climbs to dug in at 11,000 feet at Ingraham Flats on Rainier and the tent performed perfectly through-out!
This was the best gear purchase I’ve made in over a decade. I have a few sleeping bags from a great heritage -30 EMS down bag to a fairly light 35 degree synthetic sleeping bag but I decided to upgrade for this trip and I could not have been happier for my first Western Mountaineering sleeping bag! I’ll go into greater detail in a review later but for now I’ll just say I slept GREAT in this compressible lightweight sleeping bag!
This goes with me everywhere. It’s super comfy on airplanes as a blanket and in hostels around the world. I also like that it keeps my expensive down sleeping bag clean (extending its life) even after weeks of griming sleeping!
I upgraded from my older, heavier, bulkier Therm-a-Rest Prolite sleeping pad with this in “short” and doubled it up with the closed cell foam pad listed below. It was a great combo for both warmth and comfort!
This stove was amazing on this trip! Super fast and efficient for melting snow I could easily budget just 2 ounces of fuel per person per day assuming we had water sources at Lake Ann and below Winnie’s Slide bivy site.
For dinner and breakfast I went with Mountain House meals. The egg scrambles were one of my favorite. For a dinner appetizer I carried a Lipton noodle soup packet and combined it with a Miso soup packet, great for replacing lost sodium and electrolytes! The Mountain House Pad Thai and Chicken Fajita Bowl both tasted great!
My mountaineering boots of choice, full review of them here. While I LOVE these boots for my cold New England ice climbing and mountaineering adventures they turned out to be a little too warm for Shuksan and Forbidden (but perfect for Rainier, more on that later). My co-guide Jordan who has been having a banner season in the Cascades was rocking the Salomon S-Lab X Alpine Carbon 2 GTX Boots… these things look AWESOME! Basically comfy enough for long warmish approaches, crampon compatible, and climb rock really well… I will be getting a pair of these before my next summer Cascade adventure!
Make sure you select the Leverlock or FL option! Great all around mountaineering crampon in my book! I have led grade 5 ice in them and walked hundreds of miles in them from Washington to Katahdin over the last decade and they are still going strong! I do plan to shave a little weight for these longer glaciated non-water ice routes by picking up a pair of Petzl Leopard Crampons soon!
The lightest most compatible trekking poles I have ever seen! I’ve been loving these! I’ve used them all over the White Mountains including a 2 hour car-to-car ascent of the Northeast Ridge of the Pinnacle! You can see them during one attempt in this video.
I brought this harness for the less technical Disappointment Cleaver route on Mount Rainier. Super lightweight, pack-able, and able to put on while wearing skis. It is everything I want in a mountaineering harness. Detailed review coming soon.
Cell phone service is very spotty on Mount Shuksan. I was able to find a bar or two of service (Verizon) at Lake Ann (southwest side) and send and receive a few text messages. We had no service at the bivy site at the top of Fisher Chimney’s however I was able to FaceTime my wife from the summit! For the times with no service the SPOT GPS Messenger easily allowed me to send “check-in” messages home and in my opinion is an important piece of rescue gear should an incident occur.
The new Reactik+ is awesome! Up to 15 hours of burn time from an easy to recharge via USB battery with 300 lumens and able to throw light 360 feet! If you’re due for a headlamp upgrade I highly suggest you check out this model!
My current favorite GPS navigation capable smart-watch with optical heart-rate! This is the watch I used to create the GPS tracks linked in the trip report. It also allows one-button waypoint saving and the built in barometer/altimeter was a nice plus to our navigation plans. (Updated this to the newest model which is high on my wish list!)
A great little HD cam with advanced features beyond this post. You can see some of the footage about a minute into my Forbidden Peak video! (updated 2019 link to the amazing new GoPro 7 for the great onboard stabilization! <- currently reviewing)
I’ve been wearing these back east for most of my Spring/Summer climbing season with multiple trips in Huntington Ravine and through-out the White Mountains so I felt confident taking them as my main climbing pant to the Cascades. Having essentially lived in them for two weeks of non-stop climbing I can whole heartedly endorse the comfort and performance of these soft-shell pants!
This is in my opinion the most critical piece of glacier clothing you can own. I reviewed it in detail here but on a shade-less blazing glacier this one garment offers more protection and comfort than any other article of clothing I own. I’ve said it before and I will keep saying it… EVERY climber should own one of these! I do have a small cult following of “sunshade hoodies” who have “seen the light” or better yet “appreciate the shade” that these things bring… just get one and thank me later ok?

I’ve been a huge fan of Arc’teryx for quite a few years now and Backcountry is running an awesome sale on all Arc’teryx including footwear and gear! Below you’ll find my top ten picks from the sale, some of which I have linked to my in-depth reviews.
I now have two full winters with over 70 days of back-country touring with this pack and it is my over-all favorite. I find it to be the perfect size for day trips in the White Mountains and last April’s ski trip to Iceland. The dedicated avalanche safety pocket fits my shovel and probe perfectly, and outer vertical pocket holds some of my oft used tools in an easy to get to spot; I stick my snow card, compass, Rutchsblock cord, and snow thermometer in there. The “goggle pocket” is where I stash all my food for the day, and I’m able to carry a bivy sack, large puffy, and usually fit my goggles, buff, facemask, and ski gloves inside my helmet inside the pack, though there is an external helmet carry option. Finally the back panel full access to the main compartment is super convenient!
This pack is also available in a 30 and 38 liter short torso size, and a 40 liter size here.
I reviewed this pack back in 2016 and having tested quite a few packs since this one has stayed in my memory of being one of the best designed ski packs on the market. It shares a lot of the same features as my first pick like a well designed avalanche gear pocket and back-panel access. Unfortunately it is either discontinued or simply out of stock at almost every retailer. There are a few left on sale here.
This is actually my first pick if the ski mission is technical, i.e. I’ll be carrying rope, harness, a couple screws, a technical ice axe, crampons, etc. I got the ski modification on this pack and while it is the priciest of the three the materials used in construction made this a pack that will survive a decade or three of heavy use in the mountains, where as I would expect to wear our my first two picks after 5-7 seasons of heavy use. While this pack gives up some convenience features like the dedicated avalanche gear pocket it gains pure rugged simplicity. As I said in my detailed review back in 2016 this is the pack I would choose for a ski focused trip to Katahdin or a ski mountaineering day in Huntington Ravine (up Pinnacle down South or the like).
Did your favorite make my list? Let me know in the comments if it did or didn’t! I will be looking to review 2019/20 back-country ski packs early next season!
See you in the mountains,
