CRUX AX40 - is the same size as the AX35, but with a floating, removable lid (instead of a fixed one) for greater versatility in packing different load volumes. For its size and weight, the AX40 is extremely well specified, having every necessary feature that is expected of an alpine sack, yet at coming in well under a kilo, sacrifices nothing of overall robustness and durability. It is seriously tough. The harness borrowed from the AK sacks has a decade’s worth of refinement; balancing comfort and support with a minimalist profile. This carrying system is probably the best you'll ever find on a climbing sack anywhere in the world. The AX40 is available in a single, unisex back length.
