Considering getting an Osprey Mutant 38L - should I? And 22L or 38L?
To each their own, but my opinion is that a 38 liter is still small enough to be a good day pack with minimal gear. I have so many packs it's not even funny, but since I bought my Osprey Talon Velocity 30L I found myself using for almost everything. OP, I considered the Mutant 38L but I liked the fa

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

Recommendations on alpine daypacks
I’m rocking the Osprey Mutant 38L. Not the lightest but made well, has a couple options for helmet carry, crampons on the outside and ice aces or tools. Can be stripped down or full use. Really impressed by it so far.

Backpack setup for multi-day via ferrata without paid mountain huts
I was well served by my Osprey Mutant 38 liter bag for a recent 4 day Hut to Hut trip that I did in the Dolomites. If I traded some the emergency overnight gear that I had for UL overnight gear, I would have been very well equipped for a similarly experience to what you are talking about. So long as

Pack weight?
None of them seems super comfortable, but also not unbearable at all. Ok, now we are getting somewhere. If they all feel about as easy / difficult / uncomfortable to carry, that is probably because you aren't used to the weight, rather than any specific variations in design. For example, the Osprey

Dual use climbing/traveling pack recommendedations
I'm using arcertyx alpha fl 40L for alpine climbing in Kyrgyzstan and Kazakhstan currently. For me that's a good size for a 3 day trip with camping gear, climbing gear and food. An osprey mutant 38 would work well, or anything else that size with a spot to put ice axe and crampons. Waterproof is not

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

Mountain Hardware Crag Wagon 45L as a carry-on?
I often fly with my Osprey Mutant 38 This bag has flown domestically and internationally with me a few times now. I can pack a weeks work of hut to hut travel in it very readily, including harness, helmet, and a light mountaineering rack. I rented the skis and boots in Chamonix for this. The brain c
