AK Range
3G AK37 (RT)
£299
Including UK VAT.
The AK37 ushered in the third generation of crux’s AK backpacks, being the first to come off the production line in the relaunch of our iconic range. What’s new is a lighter body fabric with a 40% Kevlar® / 60% Cordura® composition (compared with 28% Kevlar on the previous generation) and a fully welded construction. A top-loading style, it now features a roll-top closing system under the hood for complete waterproofness. The classic, minimalist design and clean lines remain unchanged.
The original baby of the range (the new AK27 now assumes that role), the AK37 is frequently used by owners of one of the larger AK models as a companion for all their non-mountaineering activities, such as cragging, multi-pitch rock, back-country skiing, canyon hiking, or any other abusive activities that normal daypacks won’t handle.
The AK37 is available in two back-lengths; regular and long.
