Features

A tough, versatile and extendable rucksack that will help you through your alpine endeavours.

The result of extensive testing and feedback from the vertical world, the Osprey Mutant 38 is a strong, lightweight and ingeniously designed backpack that's designed for short alpine adventures or multi-day mountain trips. 

Minimalist by design but roomy and versatile,  the Osprey Mutant 38 will let you focus on your climbing, not what's on your back.

The Mutant 38 is constructed from Osprey's extremely robust Armourlite 420D and Armourguard 900D fabrics, and will cope with a load anywhere from 25lbs up to around 40lbs. It boasts many clever design features that will help you to get the most out of your climb - check the 'info' tab above for greater detail, and a 'video tour' of the pack.

Info

  • 2280 cu.in./38 litre capacity (Extendable up to 48 litres)
  • Weight: 2lb 14oz (1.3kg) (Stripped Weight: 0.95 kg)
  • Dimensions: 32" x 15" x 11"(82 x 37 x 29cm) approx.

The 'Reverse Wrap' ErgoPull Hipbelt is easily adjustable for the perfect fit, and secures out of the way if you're wearing a climbing harness:


 
It's 3-Point Haul System allows for secure wall hauling:

 

The axe loops allow convenient attachment of ice tools, with the 'Gorilla Grip' patch boosting durability against sharp ice picks:



The Floating/Removable Lid allows the Mutant 38 to increase in capacity to a maximum of 48 litres, or shed overall pack weight when removed.



The Mutant 38 is hydration system compatible, featuring an internal hydration sleeve with hose port, and also has the very useful Hypalon Racking Loops, a noninstrusive gear racking/organization system for climbing equipment.
 
The external pocket's circular profile prevents your equipment or accessories getting lost in the far corners of the pocket, whilst the internal pocket keeps small items handy. A removable spindrift collar provides protection from the elements, and extra retention for rope carrying.
 
An easy to remove, easy to replace 3-fold bivi pad for super-light alpine use, or just as a simple sit mat:

The thermoformed EVA foam backpanel maintains ventilation and minimizes moisture absorption, whilst a lightweight, removable framesheet helps stabilize the pack when it's loaded.
 
The Mutant 38 also features Osprey's innovative, removable Z-Compression load compression/adjustment, for easy installation of sleeping-mats, poles and skis.  Once adjusted, excess webbing can be stowed in the Mutant 38's wand pockets. A rucksack that's bursting with features for the climber who just wants to concentrate on climbing.

Osprey mutant 38 rucksack, 31 December 2013
By macca (keighley)
I have used this rucksack in all seasons and have found it comfortable to carry on day long hikes , the sack is not waterproof but with the optional rain cover it is fine, it is ideal when "scrambling and ascending tight spots "all in all a a very good sack

Not great, 14 December 2013

This pack is pretty comfortable but that is the only good part about it.

It has a load of straps all over and none of them are removable making this a very busy rucksack, on top of that it is difficult to pack because the back isn't very stiff despite having a sort of frame in it.

Once packed right as long as you don't put too much weight in it, it's comfortable to carry.

My biggest disappointment was that when it rained this pack seemed to just soak it up, it may as well be made of denim. I don't expect packs to be fully waterproof but some amount of water resistance is expected.

I settled with the montane medusa 32 in the end, pretty much the same features but with less fuss and a good water resistance.

Have been using this rucksack for the past 3 years for everything from winter mountaineering, single and multipitch climbing and hil walking. I find it to have excellant features for climbing, easy to use and adjust while wearing gloves. its not to bulky if you are having to climb while wearing it. my only real critism is that the gear loops on the belt dont take a caribiner very well, otherwise a brillint no thrills climbing pack.
