The Psiphon SV Pant is specifically created to provide durable weather protection and warmth while allowing a climber to move efficiently and effectively in severe alpine conditions. STRENGTH AND FLEXIBLITYAir permeable, four way stretch Fortius™ 3.0 softshell uses a nylon/elastane fabric laminated to mid-loft, heavyweight stretch fleece to deliver elevated thermal performance, weather protection, abrasion resistance and stretch. Burly™ Double Weave softshell reinforces the lower leg. Advanced articulated patterning and strategically placed gussets provide climbers with the ability to move effectively without compromising coverage. OPTIMIZED FOR CLIMBINGArc’teryx designs focus on achieving the highest degree of function for a specific purpose. The Psiphon SV Pant is optimized for climbing. The trim cut is carefully patterned to reduce fabric and seams that could snag crampons, particularly in the lower leg. Webbing loops are integrated to accommodate gaiter straps (not included) that will help keep snow out of your boots in deep snow conditions. The low profile waistbelt adjuster is glove and harness friendly, and removable suspenders add a level of security. Two thigh pockets: one zippered pocket securely holds small essentials, and Velcro flapped dump pocket provides quick access, even with gloves on.A SYSTEMATIC APPROACHThe Psiphon SV pant and other Arc’teryx Ascent products stand alone, but really shine when coming together as technically advanced systems that help maximize personal performance in harsh alpine environments. Clothing layers, harness, helmet, backpacks, and crampons are all considered part of the system. Knowing how a climber moves informs the designs, which are built to work in unison according to the intended style of use. Arc’teryx leverages premium craftsmanship, construction innovations and ergonomic patterns to create products that work together to deliver the highest degree of function and hardwearing protection from the least possible weight.
