Simple, light, and relatively inexpensive, the Patagonia Ascensionist is a solid alpine climbing pack, according to Outdoor Gear Lab. It features lightweight, bomber, tear- and abrasion-resistant CORDURA® nylon/polyester ripstop, asymmetrical spindrift collar that opens wide for easy packing, drawcord that simultaneously cinches collar and closes lid for a secure seal, and high-density, foam back panel that gives pack structure and helps to support heavy loads, but can be removed for lightweight pursuits.
