Close Up - Osprey Mutant Pack

Up close and personal with the features on Osprey's new technical mountain pack.

Osprey's new Mutant 38 is appearing in the shops about now, it's the company's new full-on technical mountain pack with some very neat, well-thought out features.

It comes in three back lengths and can be stripped down to cut weight from around 1280 grammes to 950 grammes.

We'll be bringing you a full test just as soon as we've had a chance to put it through its paces on the hill, but for now, we thought you might appreciate an up close and personal look at the new pack's features.

Gorilla Grip reinforced patch protects pack fabric from ice tool pics with minimal weight gain.

Shock-corded axe upper ice tool loops use cunning ergonomically shaped mouldings for snow and glove-friendly use.

Hypalon racking loops on hip-belt look neat but we found that the nose on karabiners fouled them badly. Then again, maybe we were using them wrongly?

There are tough grab loops front and rear - the rear one pictured above - plus two side loops to allow for a stable three-point sac-hauling set-up. The lid floats to allow overloading and accommodate a rope or can be removed completely as part of the strip-down process - the triple folded internal bivvy pads and frame sheet can also be jetissoned for that hard summit push.

The hip-belt can be folded back and fastened securely behind a Hypalon tunnel to allow easier access to harness gear loops when climbing.

Standard issue rope compressor allows easy carriage of climbing ropes under the floating lid.

Quick release buckles on Z-Compression straps make for quicker stowage of skis, snow-pickets, poles and so on.

Thermoformed EVA back panel gives clean lines and more importantly, sheds snow more easily than fabric and mesh back panels which can clog easily, plus EVA doesn't absorb sweat. Lightweight removable frame sheet improves load carrying. Removable bivi pad inside.

Removable lid has external and under-lid pockets for quick storage.


Full review coming soon. More information on Osprey Pacs at www.ospreypacks.com

I have tried this pack for one day only to date, scrambling in Snowdonia. It is a very comfortable carry, though choosing the right back length and adjusting the straps is essential for the right fit. With 8kg inside I didn't really notice it was there, which is all you really want.

I particularly liked its slim profile, side compression system and the large lid pocket, which takes an OS map with ease. The extending lid and body also make it very versatile.

The hip belt has a nice soft feel, full marks for comfort again, but what is going on with those mini gear loops? If you need to rack gear then I assume you would be wearing a harness, in which case the hip belt would be folded back and clipped behind the natty little strap. So no need for the ammo belt then?

I slip my poles, and axe in the winter, behind the compression straps so didnt get to try the tool loops provided, however I had a play with them and they seemed to do the job required.

First impression is of a good scrambling/climbing sack, I shall look forward to my next trip with it.

Jon, just thought I'd add that yes you were using the racking system on the hipbelt incorrectly- as shown in this video clip, you place the krab through the loops the other way round, in order to rack a selection of ice screws etc. on it, like this, hope that helps.

I tried this in a shop and the gear loops put me off, they seem to be quite a faff (needlessly IMHO) - went for the Exposure instead.
