We're obsessed with the Fernos Knicker, it finds the fine skier's line between frictionless mid-layering and highly breathable warmth – think super light, silky-smooth comfort for a chilly chairlift ride, a cold wind and a cozy apres. The articulated, capri-length midlayer packs PeakFill™ Active Insulation 40g that adds warmth during cold smoke conditions yet allows airflow when gaining vertical. A true skier’s silhouette stops short of buckles to eliminate bunching, binding or hassling when booting up in the lodge. Side stretch panels enable a full range of motion, while an articulated cut shows athletic shape at the ski cabin or in the seasonal locker room.
Relance™ Primeflex, 50 Denier Microfiber Mechanical Stretch Plainweave, 100% Polyester, 85g/m2 with 80/20 DWR finish
Relance™ Primeflex 100% polyester microfiber offers better drape and wicking than that of normal polyester fibers. This fabric features a soft hand, comfortable stretch, wind resistance, and excellent resiliency and strength.
PeakFill™ Active Insulation, 50% Polyester, 50% Recycled Polyester, 40g/m2
Our PeakFill Active proprietary insulation balances warmth and breathability to maintain lasting athletic comfort across the entire conditional range. Designed to keep core temps regulated, the synthetic fiber fill draws on a spiral filament structure to enable greater stretch, faster recovery and quicker dry times than traditional lofted insulation whether rolling slow at valley level or working hard up in the alpine.
