3G AK37-X (RT)
£329 / €399 / $369

The AK37-X is a long-awaited addition to our AK line. It is identical to the AK37, but has a floating/removable lid instead of a fixed one which adds a 3-5 litres of additional capacity. It otherwise shares the distinguishing characteristics of the AK range - a 40% Kevlar® / 60% Cordura® fabric with a highly waterproof TPU lamination and a fully welded construction. A top-loading style, it features a roll-top closing system under the hood for complete waterproofness.

We suspect the AK37-X may assume the mantle of "best seller" held by the AK47-X - it's more compact size reflects the continuing trend of lighter-weight alpine climbing as well as being a more versatile size for non-mountaineering activities such as cragging, multi-pitch rock, back-country skiing, etc.

The AK37-X is available in two back-lengths; regular and long.
