DESCRIPTION
Delivering essential protection for minimal weight, the Psiphon SL Pullover is geared for the harsh environments encountered in rock and alpine climbing. Constructed from a superlight, densely woven nylon/elastane blend fabric, Nylaz, the Psiphon delivers superior abrasion resistance. The fabric helps mitigate the effects of wind and precipitation, but is air permeable and stretchy enough for comfort on the move.
FOCUSED and ADAPTABLE

Shifting conditions require adaptable features. The Psiphon SL Pullover's Gossamera nylon hood is helmet compatible, provides wind and weather protection and features an easy, quick one handed adjustment. When not deployed, a unique hidden snap system secures the hood in windy conditions, but keeps it right at hand should the weather shift. If not needed at all, the hood is completely stowable and out of the way. Other seemingly simple details are carefully geared to maximize the Psiphon's performance without impacting the climber's freedom and line of sight. The deep front zip is designed to allow for easy removal and rapid ventilation, HemLock™ inserts secure the pullover under a harness, and the stretch gusset cuffs can be quickly pushed up while climbing.
EVERY GRAM MATTERS

In vertical situations, every gram and cubic centimeter climbers carry is a burden. Minimizing is essential, and Arc'teryx put a high level of focus on choosing materials and winnowing features to the purest essentials to save weight and maximize compressibility. The result is a full coverage hoody that packs to the size of a climbing shoe.
