Product Code: CX-AK-47-2G

AK47 (size 3)


The AK47 is the icon of the crux range. Launched in 2002, this model was virtually unchanged for over a decade – a testimony to its enduring appeal of ruthless functionality and aesthetic simplicity. It has now been replaced by the 3rd generation AK47 - more or less identical in features, the differences are primarily in fabric (higher Kevlar content), frame (now titanium) and construction (fully welded).

Designed for classic alpine mountaineering, it is small enough for shorter climbs yet big enough for multi-day routes. You can hump a heavy load of hardware to the bottom of a route with sufficient comfort, but when empty is so light that you hardly notice it on steep ground. However, what sets the AK47 apart is its stark, minimalist design. Features have been pared to the brink of absolute necessity with enough detail retained to allow each climber to tailor the pack to his/her unique style.
