The quiver killer of active insulation midlayers with a sleek silhouette for flexible, breathable, fitted winter warmth.

Frigid air and frosty mornings are just another part of your winter fitness routine when you pull on the Fernos Insulated Jacket. Arm yourself against the elements with Relance Primeflex, a 50 denier microfiber mechanical stretch outer that’s as hard working as it is soft to the touch. Lofty PeakFill Active Insulation traps in warmth without sacrificing breathability. The fitted silhouette stuffs easily into a pack, layers comfortably under your favorite shell, or works just fine on its own. Stash your mountain essentials in the zippered hand pockets, pull on the hood when the wind kicks up and hit the trail.

Shell and Lining

Relance™ Primeflex, 50 Denier Microfiber Mechanical Stretch Plainweave, 100% Polyester,  94g/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.

Insulation

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.
