Perfect for weekend warriors everywhere, the Arc'teryx Altra 50 LT Backpack for men is lightweight and efficient for three-day excursions.

It features super strong, lightweight and tear-resistant ripstop nylon that is reinforced in high-wear areas and coated with silicone to shed water, dirt and snow. 6005-T6 extruded aluminum M-bar stays provide rigid and lightweight structural support, while a high density polyethylene foam in the back panel provides comfort against the back in addition to support and structure. Durable nylon straps with Spacermesh™ lining provide stability, comfort and ventilation. Silicone treatment and polyester yarn help to repel water and dirt. Dual P'ax ice tool carry systems, a double chamber top lid, vertical zippered access points, and a large front kangaroo pocket make it easy to store, organize and access your gear.
