The new 3rd generation version of the AK57 is identical to its predecessor in features and function. The two major differences are a new fabric – 40% Kevlar instead of 28% previously – and an all-welded construction, which, combined with the new roll-top closure system at the top of the main compartment, makes it completely waterproof. The only feature alteration is the ice-axe carrying system which has been updated to stay abreast of modern tool development (so many have neither adzes nor hammers).
The AK57 is the big brother to the AK47 and features the removable floating lid of the AK47-X. Its name may not be as catchy, but that doesn’t mean it’s short of attitude – it’s just more understated. The larger capacity of the AK57 makes it a suitable pack for lightweight expeditions on high(er) altitude climbs, or for more traditional, less technical alpine routes.
The AK57 is available in three back-lengths.
|Capacity||57 + 5 litres|
|Fabric||40% Kevlar / 60 % Cordura, 240 g/m²|
|Frame||7.00 mm Ø tubular titanium, full frame (removable)|
