Tired of cold cheeks on the chair? This articulated, cropped-length midlayer hits right above ski boots and has PeakFill™ Active Insulation 40g that adds warmth yet allows airflow.

We’re a little obsessed with the Fernos Knicker. Say goodbye to cold chairs and overheated tours, we’ve found the fine skier’s line between frictionless mid-layering and highly breathable warmth. PeakFill™ Active Insulation 40g warms yet allows airflow while side stretch panels enable free-range skinning or bootpacking. Tuned specifically to skiers, the mid-calf-length, stretch-knit cuff stops short of the boot to eliminate bunching, binding or hassling. A zip side pocket stows a keycard or enough cash to grab a coffee.

Insulation

PeakFill™ Active Insulation, 50% Polyester, 50% Recycled Polyester, 40g/m2

Our PeakFillActive 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.
