Crux AK37 Climbing Rucksack
Lightweight, incredibly durable and stripped right down to the essential features, the Crux AK37 is a near-perfect alpine climbing rucksack. Rather than splashing out on fancy back systems and unnecessary features, Crux have focused on an elegantly restrained design built from premium materials. The fabric contains a whopping 40% Kevlar, giving it a huge strength to weight ratio, and it's put together with all welded seams, maximising water-resistance.
Tubular titanium back supports give the pack structure and make heavy loads more comfortable to carry, but hese are removable if you really want to save weight.
