The Purist is part of our Pure Mountain Running line, created for athletes who move through environments where gear is continuously tested by terrain. The primary body of the pack is constructed using challenge cloth, a three-layer composite that pairs high-density polyester with a UHMPE fiber reinforcement layer and a polyurethane film. This creates a fabric that is significantly more abrasion resistant than even military spec fabrics, while remaining exceptionally lightweight and ready to handle sharp rock, brush, and the constant friction of long days in the mountains.<\/p>\n
Complementing this is our EnduraMesh XT, a true 4-way stretch mesh that flexes naturally with the body. Unlike typical stretch meshes that degrade under stress, EnduraMesh XT blends Nylon 66 for strength with 30% UHMPE fibers that are rated up to 15 times stronger than steel. The result is a pack that delivers both adaptability and long-term durability, built to move with you while standing up to whatever the mountain throws your way.<\/p>\n
