Quick-draw, breathable warmth for grinding out miles in frosty weather or gaining vertical at sunrise. The highly aerobic, highly efficient vest warms yet allows airflow with 40 grams of PeakFill™ Active Insulation.

Morning fitness gets frigid as the weather turns, but our Fernos Vest provides measured, breathable warmth to keep grinding out miles in frosty weather or gaining vertical as the winter sun rises. The highly aerobic, highly efficient vest warms with 40 grams of PeakFill™ Active, a synthetic circular filament fill that warms when wet and lofts back quickly when pulled from a pack. The sleek silhouette slides easily over a stretch fleece or wicking top, yet still layers smoothly under a rain shell, soft shell or ski shell.

Shell and Lining

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, 57% Polyester, 43% 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.
