The opinion of Aventure Nordique

The AK57 from Crux is a backpack designed to be robust and abrasion resistant. Designed for mountaineers, its 57-litre volume is equally well suited to multi-day trekking, skiing and other activities. Its back is fitted with a moulded back foam for comfort, which is complemented by a removable titanium frame for back rigidity. The belt and shoulder straps are ergonomically designed and padded with a thin layer of dense foam. It has a large volume of 57 litres with a 5-litre extension.

The AK57 backpack is made of 40% Kevlar and 60% Cordura. Its high resistance allows it to be adapted to abrasion. It is also 100% waterproof with its fully welded construction. It is ideal for wet or snowy conditions. The minimalist design is due to the fact that the features have been reduced to the bare essentials, making it a lightweight backpack, but still offering the minimum.

  • Fully welded construction, completely waterproof

  • 40mm waist belt with metal buckle

  • Oversized carrying handle, easy to grip and attach

  • Removable outer and inner flap pocket with welded seams for waterproofing

  • Fully sealed roll-up closure under flap with compression strap

  • Z-shaped side compression straps, quick and easy to put on and take off

  • Two ice axe holders

  • Two side pockets

  • Side ski racks
