Inspired by our popular Knicker style, the Fernos Insulated Pant makes its debut as your go-to layer for cold weather cardio, with a large dose of comfort. Whether you're taking a snowy winter run, stacking firewood at the yurt or layering up around a campfire, you'll love these pants for their reliable warmth and undeniable comfort. The soft Relance™ Primeflex shell is paired with PeakFill™ Active Insulation and 50% recycled polyester to guarantee maximum breathability and warmth. Stretch panels and articulation allow you to move freely, and an encased elastic waistband makes these cozy favorites easy to slide on and off if you need to transition throughout the day.
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.
