Product Reviews
Rated 5 out of 5 by from Awesome pack Bought this one after having the 38 liter for a couple years. They’re just great packs. You can’t beat Osprey, especially the Mutant. The pack carry’s well and packs even better.

Rated 5 out of 5 by from My Go-To Pack For Alpine Routes This is my second Mutant pack. I have the previous generation 28 liter and I love that pack so much I decided to give the new 52 a shot. It does quite well. It is a alpine pack so if you are looking for a bunch of pockets and stuff, I recommend getting a hiking pack. I use this pack on 2-3 day trips. I carried it on Chimborazo and Cotopaxi and it was more than large enough. It's large enough to carry in the Cascades as well (although on Rainier I use my Aether Pro 70). These packs are better than everything I've seen short of Hyperlite. I consider a BD Mission but it is heavier and I am weary of manufactures who don't specialize in gear (Osprey only builds packs where BD builds all sorts of stuff). It does not come with a rain cover though like it says here in the description. Moosejaw, fix that please. Perhaps my favorite feature is the removeable brain and top flap that is underneath. And the gear loops are great. I've also used the haul loops to haul it up rock faces. They do the job but if you do it enough, you will wear holes in the material (from rubbing on the rock). The Deuter Guide line is similar. But I am just comfortable carrying Osprey on my climbs. They fit me well. Also, it's easy to add a crampon carrying system to the back. Check out the pictures.

Rated 4 out of 5 by from Light and comfortable I bought this pack looking for something that could strike a balance between having the right attachments for technical gear, being spacious enough to carry winter mountaineering/ snow camping gear, while remaining comfortable. I was able to try it out this week on Mt Hood. It performed extremely well. I was a little concerned about the ice axe attachments and the shallowness of the ski/picket pockets, but they worked fine. The helmet attachment is brilliant. Where the pack shined for me is that until I needed something out of it I forgot I was wearing it. It compresses down well and moved with me on the more technical terrain staying snug on my body, not sloshing around. I can’t speak to durability yet, but the materials seem high quality and it’s built well so I have high hopes. Great bag for carrying bigger loads on alpine adventures.

Rated 4 out of 5 by from Easy to adjust and comfortable to wear We bought this for our 15 year old son. He is currently 5’9” and growing, my husband who is 5’7” was able to wear it comfortably too and there is room for growth for our son. We plan on using it for carrying rock climbing gear as well as some one and two night back country camping. It has plenty of space for all the gear and food that he will need for those trips in it.

Rated 5 out of 5 by from Perfect mountaineering pack This pack is perfect for alpine adventures. It’s super comfortable, super durable, and has the perfect amount of features. Highly recommmend!
Date published: 2020-12-19
Rated 2 out of 5 by from Lacking in feature set and capacity I compared this pack directly to the Gregory Alpinisto 50. I purchased both to make side by side comparisons of a larger technical pack to take on multi day alpine adventures. This pack is to be used for approaching high camps, and then being used for summit attempts. I dabble in general mountaineering with glacier travel, alpine rock climbing, and ice climbing. I loaded the same weight and gear into both packs and it was apparent that the Mutant held less volume than the Gregory even though it is listed as 2 liters larger. The straps for the lid do not extend out to accommodate a a taller load. The side picket pockets are pretty much useless besides holding the bottom end of a strapped picket. There is not a hip belt pocket, just a gear loop on each side. I know some hardcore climbers don't want a hip pocket, but I find it invaluable to stash gels and bars to refuel in a short 3 minute break without having to remove pack. You have to stow your crampons in the pack or strap them to the front. The Alpinisto has a burly crampon pocket that is perfect and easy to access crampons when you need them. The helmet carry is a bit cheesy. You are better off just buckling your helmet to the gear loops on the front. I bet the smaller size is a lot better option in the mutant line.

Rated 5 out of 5 by from Super comfortable with rock climbing gear. I bought this to carry rope, harness, shoes, & helmet for daytime rock climbing. It’s light, well-constructed, and super comfortable. There aren’t any bottle holders on the outside but they fit fine inside. There are gear loops on the outside which work great for carrying extra things or sweaty gear.
Date published: 2020-07-18
Rated 3 out of 5 by from Climbing with a osprey, make sure it works with a helmet. Osprey packs, often have a internal frame extending above the shoulder straps. This can hinder head movement looking up, when ski touring, climbing, especially with a helmet on.

Warranty Info

ALL MIGHTY GUARANTEE - Osprey's Lifetime Warranty

When Osprey celebrated their 35th anniversary in 2009 they launched The Osprey All Mighty Guarantee. What that means to you is ANY Osprey product purchased at ANY time is covered. Any product, any reason, any era - the all encompassing Osprey lifetime warranty ensures their dedication to superior design, craftsmanship and quality of their products is backed up by their actions to replace or repair a pack so it lasts a lifetime. Or two.

Here are some details.... Osprey will repair for any reason, free of charge, any damage or defect in their products, whether it was purchased back in 1974, or ordered right now from this site. If they are unable to perform a functional repair on your pack, they will happily replace it. Osprey proudly stands behind the All Mighty Guarantee, so much so that it bears the signature of company founder and head designer, Mike Pfotenhauer.

Some Osprey All Mighty Guarantee FAQs:

What do I do if my Osprey pack needs to be repaired?
If you live in the United States and need a repair done on your Osprey pack, you will first need to obtain a Return Authorization number. You can do this by reaching their Returns Department at 866-314-3130, or using the information that is provided with a new Osprey pack.

What do I do if I just need a replacement pack part like a buckle?
Give Osprey a call at 866-314-3130 and they will take care of you.

How long will it take?
You can tell Osprey you need the pack returned by a certain date when you request a Return Authorization number, and they will do their absolute best to meet that deadline.

What if my pack is super dirty and stinks?
Clean it before you send it to Osprey to get repaired. The real reason is that there is a law that says if your gear is too dirty or odiferous (smelly), Osprey is not allowed to repair it and will just return it to you.

Do I have to pay for shipping?
A little bit. You are responsible for the cost of shipping the pack to Osprey, and they will pay shipping to return the pack via UPS or FedEx. Osprey cannot be held responsible if packages get lost in transit, so make sure you get a tracking number when you ship your pack out. Also, if you use expedited shipping be sure to let Osprey know (866-314-3130). They, in turn, will give your pack priority processing and return it using a similar expedited shipping method.

Do I have to register my pack to take advantage of this incredible guarantee, and/or need to be the original owner of my Osprey pack?
No! Osprey's All Mighty Guarantee is truly ALL MIGHTY. If you own an Osprey pack that needs to be repaired they will repair or replace it.

JUST A HEADS UP: If your Osprey product is not repairable and is replaced, the original product will not be returned to you. They will try really really hard to repair your pack, but if they are unable to make a functional repair, they will replace it. For products that are no longer in production you will be contacted by Osprey to discuss replacement options.

All good answers. So what is NOT covered?
• Osprey program packs or any Osprey pack used by outdoor programs are ONLY covered under Osprey's Program Pack Warranty, NOT AMG.
• Size and/or fit issues. Make sure you buy a pack that fits. Check out the size guide on Osprey product pages for more info.
• Personal preferences like colors you don't like, style of the pack, or not enough/too much room in your pack. Check the product description, features, specifications, and size guide to make sure you are ordering the right pack for you.
• Third party Repairs or replacements. Send your Osprey pack to Osprey and Osprey only to get fixed. Easy as that. And don't try fixing things yourself.
• Cosmetic wear and tear including any reasonable aging of your pack that affects only the appearance and not the function of your pack. Be proud of those scars!
• B.A.M.G. (Before All Mighty Guarantee) Repair Work. The All Mighty Guarantee applies only to repairs requested on or after January 1, 2009.
• A Osprey Hydraulics reservoir is covered by a limited 1-year warranty, which is the reasonable lifespan of a reservoir. Pouring and storing of warm/hot or boiling water in your reservoir WILL VOID your warranty, so don't do that. Reservoirs are NOT designed to contain or handle liquids at temperature.
