Designed for the most extreme conditions. Extremely reliable and resistant, the A4M backpack from the Expedition-Light line will take you to the highest peaks.

Stronger, lighter and simply cooler, A4M 40L is made from 100% Dyneema® Composite fabric and is 100% waterproof.

It is 10% lighter and 30% stronger than comparably heavier high-end nylon fabrics. This makes this backpack the ideal companion for mountaineering and expeditions.

The roll-up closure and waterproof main compartment with taped seams offer maximum protection against the elements. Two daisy chains on the package provide attachment points for the gear.

A "weatherproof" waterproof zippered back pocket offers quick access to an internal top pocket and an external waterproof zippered pocket is arranged in the top flap. They offer convenient space for objects and equipment. The wide, removable waist belt makes the A4M comfortable to carry even under heavier loads.
