Mutant 38L Backpack

Osprey's Mutant 38L Backpack carries your essentials whether you're on a technical alpine objective or running laps on ice climbs. Complete with the necessary features required for light and fast missions, the Mutant 38L strips itself of the extra components of a typical technical pack. Reinforced A-frame ski carry holds your skis securely and the 3-point haul system distributes the weight of the pack evenly when clipped at an anchor or hauling up a climb. The hip belt features two gear loops to clip and carry equipment that can be easily accessed when wearing the pack while climbing. Ice tool locks safely stow a set of ice tools, and an included helmet carry attachment conveniently holds a climbing helmet during the approach.

  • A streamlined pack hauls your gear on light and fast alpine objectives
  • 38 liter capacity is perfect for long, single day missions
  • A frame ski carry securely holds your planks while straddling a ridge
  • 3-point haul system fastens pack to an anchor on multi-pitch climbs
  • Hip belt and ice axe gear loops allow for additional gear storage
  • Helmet carry stores your helmet when hiking back to the car
  • Item #OSP00BC

Everything you Need for Technical Routes

I fret over packs. I routinely destroy packs through use. This thing is the closest to perfection I've seen after 10 years of climbing. I previously shied away from Osprey packs because they've always seemed over-engineered and a little too ultralight (i.e. delicate) to me. But I'm really glad I went with the Mutant 38. I got it to replace my Cold Cold World Valdez, which is bomber but doesn't carry heavy loads very comfortably. I wanted something small enough to climb with, but big enough to fit everything for 2-4 day routes (with judicious packing). After a summer of abuse in the Cascades (including two nights on Stuart's North Ridge and a day of using it as a haul bag on Liberty Crack), I'm as convinced as the reviewers at OutdoorGearLab, who fawned over it. Volume: It may advertise as 38 liters, but this thing is a bottomless pit. It took sleep kit, food for 3 days, 2.5 liters of water, a single rack, extra clothes, etc. without batting an eye, and it was still comfortable for a long approach. Climbing: Just as important, it climbs really well, even with the frame in, so you can keep that internal structure for a long approach without it being uncomfortable when things get vertical. I really liked the extra hood feature that covers up the top of the pack when you stuff the brain inside -- it keeps moisture out and gives the big cinch straps a place to go instead of just dangling. Cons: The cons are pretty minor here. I agree with Connor that the attachments are a little fiddly when using more technical/aggressive tools. Also, the cinch straps for the brain run directly over the handle attachments for your tools, which ends up being pretty annoying (and is the reason for 4 instead of 5 stars). Finally, there is absolutely no internal organization to this pack, except for a hydration sleeve. I actually prefer this, but it's something to keep in mind if that matters to you.

Really Nice Backpack For a Great Price

This backpack is really awesome for ice climbing. Very very comfortable, pretty light, and the axe attachment points work pretty well and the price is amazing. My only gripe is that it can be a bit hard to load properly if you are putting rigid or awkwardly shaped items in it. Also, the tool attachments are a bit fiddly when used with a very curved and handled ice tool (Cassin X-Dream for example). The head attachment works great but the tools require some fiddling to line up well with the handle loops. This would not be an issue with an ice axe or a straighter ice tool.

Great pack even when fully loaded

Familiarity:
I've used it several times

I was split between this pack or the Mystery Ranch Scepter 35. I went with this one because my larger 70 liter pack is osprey and the osprey fit for me is very comfortable for my hips and shoulders. And this was no exception. I had it fully loaded with my tools, crampons, slings, biners, puffy, food, 70m rope ,and whatever else I threw on it and there was very little movement when traveling and moving under trees on our approach. It felt very comfortable and natural on my body and made the approach not as grueling. The amount you can stuff in here as well is very impressive Climbing with it on felt alright. I don’t like climbing with packs on but it wasn’t too bad with this pack. I’m giving it four stars because all of what I said is based on my initial impressions. The amount of straps can be a bit of a headache when fully loaded but when you get an osprey pack, it’s bound to have straps on straps. And the top lid (brain lid, whatever you want to call it) will sit funny if your pack isn’t loaded up. All in all I very much enjoy this pack. It serves its purpose well and does it very comfortably. The photo is the pack fully loaded and what it looked like out to the approach (rope, tools/gear, food, etc).

More Please!

Awesome Pack! This pack is nice and lightweight! It's the perfect pack for those long(or short) approaches to the crag, summiting peaks or just going for a casual hike. The frame and waist moves well with your body as you're climbing up and over obstacles. It felt comfortable on my back even as I hiked 16 grueling miles completely packed down. I always wanted to see more from Osprey geared towards climbing and here is what I was looking for! Oh, and the helmet carrier on top is a really nice feature! Keeps you from having to strap it onto you pack and hearing it smack around. Very happy with the Pack! Keep 'em coming Osprey!

Awesome

Too small

Familiarity:
I returned this product before using it

Ended up returning this pack. It's a great pack and so I hesitate to give it fewer than 5 stars. It is just smaller than I was looking for. I want something in which I can haul more climbing gear.

We have a 52L for you, Hailey! :-) Leta Osprey Rep

Love the previous version of this pack. It had a zippered lid, and a rope AND helmet carry. I see no mention of a rope carry strap in this description? Are they relying on the buckle lid to retain a rope alone?

Hey Rich! There is another strap under the lid (much like most rope carry systems). Feel free to contact me if you have other questions using the info above! Cheers, Josh
