Our Take:

Certified

The Patagonia Descensionist 37L ($295) is a smartly designed, comfortable ski pack that quickly became our tester's go-to backcountry companion for the season. It’s more feature-rich and comfortable than Patagonia’s 38-liter PowSlayer pack, and offers excellent access and more than enough structure to support surprisingly heavy loads. At 3 pounds 4 ounces, it's the heaviest pack in our test lineup, but for downhill-oriented backcountry skiers who don't mind the weight, the Descensionist has quickly become one of our favorite all-around touring companions.

The Patagonia Descensionist 37L is one of the most comfortable ski packs I’ve used in years—I immediately began comparing it to my long-time favorite, the venerable BCA Stash 35. Its shoulder straps strike an excellent balance between padding and low-profile mobility; they’re not overly bulky, and they distribute weight well across my torso. The stiff backpanel is also excellent: It has plenty of structure but flexes naturally with my spine rather than fighting against my movements. That combination makes the pack impressively supportive without feeling rigid or cumbersome.


What surprised me most was how well the Patagonia Descensionist 37L handled heavy loads. I turned it into my go-to backcountry camera pack and regularly carried more than 20 pounds of gear, including a mirrorless camera, multiple lenses, a drone, avalanche tools, extra layers, goggles, water, and snacks. Despite packing it to the gills, the Descensionist’s comfort barely wavered. Even when I skied aggressively with all that gear on board, the pack stayed close to my body and never bounced around or shifted unpredictably, largely thanks to the compression straps that tightened the load. The stiff backpanel also did a great job isolating me from the pack’s contents, which mattered when I had camera lenses floating loose inside.

The only recurring annoyance I had with the Descensionist is that the shoulder straps gradually loosen throughout the day, requiring an occasional quick tug to tighten them back down. I noticed this most when I loaded the pack down with heavy gear. It’s not a dealbreaker, but it was a consistent enough issue that I should mention it.

The Descensionist’s storage layout is intuitive, especially for transitions from skinning to skiing. The pack pairs a top-loading drawstring opening for the main compartment with a large side-access zipper, which I came to rely on heavily. I got into the habit of laying the pack on its side while I ripped skins, then using the side access to grab layers, snacks, and camera gear, or repack skins fast and easy without fully unpacking the bag. On the skin track, I used the two hipbelt pockets to stash small snacks, sunscreen, or a phone.


This pack’s avalanche tool compartment is one of the best I’ve used. It includes dedicated sleeves for a shovel and probe, but unlike many competitors, it leaves enough extra room for skins, wet gloves, or other snow-covered gear. Compared to ski backpacks like the Stash or the Ortovox Switchback 32, the Descensionist’s avy pocket feels significantly more spacious and easier to work with. The pack also includes a small internal zippered pouch and a goggle sleeve, although I found the latter a bit undersized for spare lenses or backup goggles.

Ski carry options are thoughtfully executed as well. The Descensionist supports both A-frame and diagonal carry, and I used the diagonal setup several times while booting steep couloirs. You can still access the side zipper with skis stashed in this configuration, which makes transitions even more efficient.


My biggest frustration with the pack’s organization is the drawstring closure. The cord is excessively long and lacks a clean storage solution, so it constantly snagged on ski brakes, my arms, or other gear throughout the day. Additionally, the helmet carry works fine once installed, but setting it up initially felt fussier than it should, and the extra carry straps float loosely inside the pack when they’re not in use.

The Patagonia Descensionist 37L thrives as an everyday touring pack for skiers who want to be prepared without carrying something oversized or cumbersome. Throughout the season, it became the pack I reached for most, because it handled such a wide range of ski days well. Whether I was gearing up for a long day out or crushing a quick fitness lap, the Descensionist always felt capable yet not overly bulky. That gives it a major advantage over touring packs that start to feel disconnected from your body once terrain gets steep or technical, such as the Mammut Nirvana. I’d happily use this for resort-accessed backcountry skiing and full touring days alike, although it’s overkill if you’re looking for a resort pack.


That said, this is still firmly a single-day touring pack. There’s enough room for a substantial amount of gear, but overnight objectives or hut trips would quickly overwhelm its capacity. And while I appreciated the relatively sparse organization, skiers who prefer highly segmented storage systems may want additional pockets. Still, for most normal tours, the Descensionist strikes an excellent balance between simplicity, capacity, and usability.

Patagonia constructed the Descensionist with 210-denier, TPU-coated ripstop nylon, the same material used in the brand’s PowSlayer 38L. The fabric strikes a good balance between weight, toughness, and water resistance (though it’s not as waterproof as Dyneema). After roughly 20 days of use—including tree skiing, scraping through tight branches, throwing the pack in truck beds, and rubbing it against sharp ski edges—it still looks nearly new. I haven’t been gentle with this pack at all, which makes its lack of visible wear especially impressive.


The hardware quality also stands out. The buckles and straps feel sturdy and operate smoothly with gloves on, which matters a lot during cold transitions. I especially appreciated that the waistbelt buckles never accidentally popped open, something I’ve occasionally experienced with the BCA Stash. The zippers—both standard and taped—have also held up beautifully and continue to operate smoothly. Overall, the Patagonia Descensionist 37L feels exceptionally well-made, although it doesn’t get perfect marks for durability as it’s not quite as tough as Dyneema or thicker nylon packs like the Raide LF 30L and Osprey Soelden 32 (420D nylon).

At 3 pounds, 4 ounces, the Descensionist is the heaviest ski pack Better Trail has tested so far. It weighs much more than the more minimalist PowSlayer 38L (2 lb. 9.6 oz.), the fully featured Switchback (2 lb. 5 oz.), and the popular Osprey Soelden 32 (2 lb. 8 oz.), and even more than the larger Hyperlite Mountain Gear Headwall 55 (2 lb. 9.7 oz.), which is made with Dyneema.


Even so, it never felt awkward or restrictive while I was skiing aggressively, even when I was carrying camera equipment and extra layers. Unless you’re on a fast-and-light mission where every ounce counts, I think the Descensionist strikes an excellent balance of weight, comfort, and durability.

Longevity

Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.

Patagonia sells the Descensionist in unisex sizes small to large, and I tested the medium version. The pack fit well almost immediately, thanks to generous adjustment points on both the shoulder straps and hipbelt. Once tightened down, the pack hugged my torso closely without restricting movement.


It’s worth noting that the Descensinist’s size range isn’t as generous as packs that come in both men’s and women’s sizes, such as the Ortovox Switchback, the Osprey Soelden/Sopris, and the Mammut Nirvana. As a result, those who fall outside standard unisex sizes small-to-large might have difficulty finding a good fit.

Patagonia PowSlayer 38L ($265): Cutting Ounces, With Caveats
Patagonia offers three ski touring backpacks—the downhill-focused Descensionist, the skimo-pack-adjacent SnowDrifter, and the PowSlayer. The PowSlayer is cut from the same cloth—literally—but takes a more minimalist approach with a single U-shaped backpanel opening. At 2 pounds 10 ounces, it's significantly lighter and might be a better all-around choice for skiers who spend a lot of time going uphill. But we have our qualms: We didn't find it as pleasant to wear as the Descensionist under a heavy kit—the thin, comparatively flimsy backpanel means the pack's contents might press into your back—and the lack of top opening took us a while to get used to. Even at $30 more, we recommend the more robust Descensionist if the weight difference doesn't matter. For more, read our Patagonia PowSlayer 38L review.


Ortovox Switchback 32 ($240): Lean Into Organization
The Switchback 32 opts for a more technical ski mountaineering loadout than the Descensionist, with a clever ski-carry system, rope carry, and extra external pockets that serious ski mountaineers may appreciate. However, the Descensionist feels simpler and more intuitive for everyday touring, and its larger capacity allows you to carry more gear (the spacious avalanche tool compartment is also a breath of fresh air compared to the Switchback’s, which barely fits the necessities). If your tours regularly involve ropes and technical scrambling, the Switchback gets the edge. Otherwise, the Descensionist feels more approachable and versatile. For more, check out our review of the women's Ortovox Switchback 30 S.

The Descensionist is a high-capacity day touring pack and one of the most comfortable models we’ve tested under heavy loads. It’s neither light nor very affordable compared to the competition, but it stands out for downhill-oriented backcountry skiers who prioritize comfort and durability over cutting weight.

The Switchback is one of the most well-rounded ski packs we’ve tested. It’s sized just right for run-of-the-mill single-day tours, but it has a feature set that can handle more vertical endeavors. There are a couple of design quirks, though, and some competitors cost less.

Is the Descensionist 37L for You?

The Patagonia Descensionist 37L is a comfortable and functional choice for downhill-oriented backcountry skiers who want a relatively high-capacity touring pack for day outings. The side-zip access might take some getting used to if you’re coming from a U-shaped backpanel, but we appreciated its simplicity, and the cavernous avy-tool compartment makes stashing and retrieving safety gear especially smooth. If you’re a skier who values durability and comfortable carry over shaving every ounce possible—we’re guessing you like to rock fat skis and Gore-Tex, too—the Descensionist is one of the most well-balanced ski packs on the market.
