Looking for a good mountaineering backpack between 35-40L, max budget 150 euros, with ice axe compatiblity. Any advise?
I have the Osprey mutant 38, absolutely no complaints and holds weight very nicely

40L Mountaineering pack?
I love my osprey mutant 38. It can do pretty much anything you ask of it. Also, check out hyperlite's prism or crux packs.

I can’t help but hoot & holler when I ski
Osprey Mutant 38 with the brain removed. I wouldn’t recommend it specifically for ski touring though—it’s more of an alpine climbing/mountaineering pack. I got it several years ago as a do-it-all pack because I was on a budget, and have yet to replace it because it works fine.

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

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.

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.

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
