Optimized for climbers seeking a strong, light pant for all-round use, the Psiphon AR combines weather protection, efficient thermal regulation and breathable stretch performance. The hardwearing Burly™ softshell fabric is a four way stretch woven that combines the superior strength and durability of a nylon face with the comfort and moisture transport performance of a microfibre polyester backer. A DWR finish adds water repellency. Two low profile zippered hand pockets securely hold smaller items, and a larger thigh pocket is easily accessible. The streamlined waist closure fits easily under a harness.FIT THAT FUNCTIONSThe Arc’teryx design team is inspired to solve climbers’ problems and improve performance. From the knee down, the Psiphon AR’s tapered fit is trim and stays out of the way while climbing or kicking in crampons. Seams are eliminated on the inner lower leg to reduce snags and potential tears, and the gusseted cuff closure accommodates mountaineering and ice climbing boots as well as most ski mountaineering boots. The result is a thoughtful, informed pant design that reduces climbers’ frustration and potential dangers, freeing them to focus on movement and ascent.A SYSTEMATIC APPROACHThe Psiphon AR 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.
