High-Performance Gaiter for Mountaineering and Extreme Environments The Expedition CrocodileA(R) Gaiter features durable construction and rugged, waterproof materials, purpose-built to protect the lower legs and feet in extreme mountain weather and terrain during extended mountaineering trips to 8,000-meter peaks and beyond. Our Expedition "Crocs" features 3L construction, combining GORE-TEX for breathable waterproofness, a rugged CorduraA(R) shell for elite abrasion resistance and protection against crampon puncture and ski edges, and a 420D packcloth lining for breathability and additional insulation. The durable double-stitched hook-and-loop front closure keeps snow and debris out and away from layers, and the BioThane instep strap delivers a rugged, adjustable, and customized fit. The large circumference delivers plenty of room for layering over plastic mountaineering boots and heavily insulated pants, providing complete coverage in extreme conditions. For venturing deep into the mountains in the harshest weather and conditions, the Expedition CrocodileA(R) Gaiter is a trusted ally for far-reaching mountaineering objectives worldwide.
