Best 33-35l alpine packs?
Osprey Mutant 38. Excellent and very well priced.

Need help choosing the right backpack
Probably not helpful, but I picked up the Osprey Mutant 38L for its size and versatility. It has an external cover to tightly attach and hold a helmet in multiple places. It has external rope tie downs (I use my 70m with it). It has a removable top that adds more stash space. I can put everything in

Phantom 38 or mutant 38
A bag is a bag... I use the mutant 38 and like it. I think Osprey's backpacking heritage really shines in that it has a very supportive frame, and I've overloaded it with 40+ lb.

40L Mountaineering pack?
I have a friend with one and he let me use it for a day Splitboard mountaineering and I fucking fell in love. Even being able to get a proform though I can’t justify it to myself when I already have an airbag and the osprey mutant 38. If you can spend the money absolutely do it, otherwise go with th

Should I get a Mountaineering Specific Pack?
Yes, it is nice to have a climbing pack for climbing! It fits better with climbing motions, has better straps for climbing-specific gear, and also, I don't want to damage my lightweight overnight pack while scrambling. I have the Osprey Mutant 38 and love it, but don't think it's a market standout.

crag pack recs?
Osprey Mutant 38 is a great bag. It’s worth the $200 price tag, but it’s also often on sale for a lot less.

Backpack recommendations
I'd highly recommend an Osprey pack (I love the Mutant 38 for climbing) because they have a lifetime warranty and will replace your damaged packs for no charge. My bigger cams tend to rip the inside of my bag, so I've really appreciated this.

Need help chosing a pack
Osprey Mutant 38 is a great option, and looks to be on sale now, easily under your budget. I've taken it on a six day trip as well as on day trips. If I'm just doing a day scramble I prefer to reach for a smaller pack, but the brain on the Mutant is removable so you can get it small enough to not fe

Looking for a versatile 22–28 L pack for mixed climbs
Funny, I've been obsessing over the exact same thing all week and settled on the trion 28 as the one want to get, too. The side zips are the main reason why, but I'm nervous about there being no outside pockets or a brain for snacks/headlight/keys etc. Has that been an issue with your 35L? I have th
