Product description Osprey Mutant 38L

The Mutant 38 is a top loading, lightweight pack designed specifically for the alpine mountaineering / ice climbing minimalist.


Integrated FlapJacket closure system:

- When your pack is being used without the removable top pocket, the FlapJacket lid deploys to provide main compartment protection from the elements and top-down compression to keep the pack load stable.

- To deploy the FlapJacket, remove the top pocket and deploy the FlapJacket over the main compartment using the top pocket retention straps to buckle and cinch into place.

- Beneath the FlapJacket there is a zippered mesh pocket to keep smaller items organized and accessible when the top pocket is not being used

Removable helmet carry system:

- A zippered pocket near the top of the Mutant pack stows a removable stretch mesh helmet carry system to secure your helmet to the pack when not in use

Removable side compression:

- Adjustable, removable one piece side compression/ retention straps with upper side quick release buckles provide load stability and external carry options while O-ring routers allow for sectionalized compression

A-frame ski carry:

- The reinforced A-frame ski carry loops found near the base of either side of the Mutant work in conjunction with the side compression/retention straps to provide stable, easy to use A-frame ski carry.

- Simply slide your ski’s tail through the loops until the bindings rest on the loop and use the upper compression/retention strap to secure to the side of the pack


- The fixed, reverse spacer mesh die-cut foam harness is designed specifically with stability, carry and comfort in mind.

- An adjustable sternum strap with rescue whistle buckle provides proper torsional stability while reservoir hose routers keep hydration accessible and at the ready


- A swen-in hydration sleeve located on the inside of the backpanel accepts up to a three-liter reservoir while the backpanel hydration exit port allows either right or left routing using the elasticized straps on the packs harness

Removable top pocket:

- A floating, removable single compartment top pocket with internal key clip and helmet retention system keeps much needed items organized and accessible

Reverse wrap hybrid hipbelt:

- The padded, EVA foam hipbelt with integrated gear loops and attachment points features reverse wrap hybrid technology designed specifically for use with climbing harnesses


- A removable 1.2mm HDPE framesheet with a removable aluminum stay, works in conjunction with a reverse spacer mesh, ventilated ridged foam AirScape backpanel. This suspension ensures a high level of comfort, breathability and load transfer

Tool carry:

- The Mutant Dual ToolLock system allows easy access to, and secure attachment of all ice tools including leashless tools

Backpack designed for those who climb for those who climb


A backpack really comfortable and roomy, equipped with many small precautions that make it the number one for mountaineering in all its forms. The side compression straps allow you to keep the backpack compact but at the same time to bring material. The belt is equipped with other materials and if it becomes cumbersome during the climb it is possible to reduce the encumbrance to avoid annoyances with the harness. I am 187 cm tall and I took the size ML ..... PERFECT !!!

Great backpack!


Great backpack. Very satisfied. Price is an order of magnitude less than in stores. Fast delivery. As promised, 2 weeks. Trekkinn works quickly. Thank you!

Not anymore this only using!


Because you are working as a climbing instructor, back pack will be one of the most important tool that is directly linked to day-to-day operations. Osprey Mutant is a very lightweight, easy-to-use, I think that it is one of the most suitable backpack in Alpine climbing. In my case, sawanobori two nights and three days, it is a good size and is used in winter climbing two days and one night (both camp). A convenient hole for attaching a tool rack attached to the waist belt, can be mounted six in conjunction with both sides. Two and eight ice screw ice ax has been carrying. Without difficulty, and since can be carried separately for each length, it does not have to waste time to retrieve. Summer is here to attach the cam and Haken. The back pack front there are four of the small loop, here you can fix the crampons by installing a rubber draw code. Net can be fixed has been built in the helmet on top of Amefuta. If people are summarized in a compact package, this backpack will surely become a great ally of your hiking! it's recommended.
