good pack

A light pack which is quite comfortable as long as you don`t overload it, obviously! Even when well loaded the back panel arches to help ventialtion.

I would have sacrificed some of the features for more robost fabric on the base and more comfortable shoulder straps for when it`s well loaded. The next pack I`ll buy will be more durable and comfortable - low weight isn`t a big priority to me

Great Pack!

Got this to compare with TNF Phophet 40 - ended up keeping this one even though it is heavier as it seemed to fit more (and is 3 liters smaller) but due to shape, it was easier to pack more into. I wish the pack weighed a little less - I can see how this could easily be accomplished by slimming down on some of the huge nylon webbing. Nonetheless, a great pack with some pretty cool and useful features.

Incredible pack

This is a wonderful pack, I have used it in several mountaineering trips and really stands out well. Lightweight and confortable. I wish they make this pack in other colors like blue, red or yellow, more mountaineering oriented color that make the pack easier to locate.

Fantastic Alpine Pack

I find this to be a perfect climbing pack for myself. I use it during the summer for carry sport climbing gear, and will be using it in the winter for ice climbing and mountaineering. Carries very comfortably, (when packed right) very light, and no frills on it either, make this a super technical pack, since there's nothing to get stuck on when you're climbing. The material wears very well, and I have not had any problems with this pack in terms of wear and tear. Hydration compatible, and has the awesome racking loops on it too, which are good for storing extra ice screws, or other things you need close at hand. The other thing is too, the zipper pulls are perfect, and can be operated with gloves! You can tell Osprey did their homework when they made this pack.

Can this pack handle ski carry?

Can this pack handle ski carry?

Responded on

Yes, but keep in mind that because its not designed specifically for that, you may seem some premature ware on the sides dues to the sharp ski edges.

Best Answer Responded on

The Mutant can certainly handle ski carry. There is always a concern about burred ski edges causing some damage to any pack material they come in contact with. Having said that, the 420 denier packcloth that comprise the side panels and the 100 denier lower side pockets should provide plenty of protection given a modicum of care.
Osprey's Variant 37 is very similar to the Mutant but with shovel slot on the outside and a very lightweight aluminum frame that may slightly improve the carry with that extra 15+ pounds of long levers pulling on you in the wind. Just a thought. Either way, I think you'll be very happy with how the packs carry with skis or without.

Hello backcountry :)
Can anyone tell me how large the bivi pad is? Im wondering if it will cover from ass to feet if one is sleeping while sitting :)

Responded on

You should be just fine, unless you're quite tall...like over 6'2 or so. But then you can also use the rope and the backpack and...well, I'm sure you get the idea. Good luck!

Responded on

well, im 5'10, so yeah, should work - thanks for your help :)

Minimalist Dream

This is a simple, clean, small amount of frills 'ALPINE CLIMBING PACK'. What does that mean? No frame, light and clean, tough, with some climbing perks to it.
The bonuses: Removable top lid, easily stows inside the skirt, and seals up. Simple shoulder and waist belt straps/padding - you can clip and stow the waist belt around the back which is super nice for climbing! a mesh pocket on the side for storing pickets- some alpine packs miss this and you must put them inside your packs. Easily removed light simple bivy pad...I more use this for sitting on in the snow or in camp so I save my sleeping pad from too much abuse. Tough fabrics-I drag this thing around and it is plenty bomber to rock, snow and ice.

Things to remember: This is a sack-no frame, so it won't carry as well as other bags if you don't pack it right! But that makes it light and with its narrow profile easy to climb with - perfect size for overnight alpine missions, especially since you can store a rope securely under the top lid.

If you are an aspiring alpine ninja, this is the pack for you! But don't forget, I have found it works quite well for cragging (ice and rock) and ski touring as well!

Has any woman with a small frame tried this pack? How's the fit?

This pack looks sweet. I only wish there was a woman's specific fit! Osprey's women's packs with mesh back generally fit me fine but not sure about this pack with the stiffer foam. I am 5'3, skinny, torso size 16''.

Best Answer Responded on

I am a small guy (5'3" and 150 lbs) and I have the small frame pack. It fits great!

Would this pack be too big for overnight trips? I'm looking for something between a multi-day backpacking bag and day trip.

Best Answer Responded on

That really is subjective to how you pack. I know people who use a full 4000cu in. for an overnight and some who use a day pack. I would use this for an overnight, it doesn't really matter if you have extra space.

The best thing is to determine if it will fit everything you want to take and how much room is or isn't left over in the end.

Great Technical Pack

I needed a pack for technical rock & ice climbing that could fill the void between my BD Bullet and my Gregory Z55.I've climbed twice with this pack now, and highly recommend it. It's light, cinches down tight, and conforms well to your frame; subsequently affording you excellent freedom of movement, good upward visibility, even with a helmet, and excellent weight distribution (when packed correctly).The pack exterior is clean, yet there are some nice amenities, such as hydration compatibility, two pockets in the lid, adjustable lid height, rope strap, and tool straps. All the latches and tie downs are glove friendly too.

Is this pack hydration system compatible?

Responded on

Yes, according to Osprey's website, it is!

Responded on

Yes, it fits a 3L reservoir just fine.

Responded on

The Hydration pocket will also fit a 3L system fine also, I use one myself.
