Parking lot to peak, first chair to last, sunup to sundown—chasing that mountain magic means putting in the time in all conditions. Our Fernos Insulated Jacket is just that. This choice active insulation midlayer is equipped for high-output pursuits, working just as well under a shell as it does on its own. A Relance™ Primeflex outer combines with PeakFill™ Active Insulation and 50% recycled polyester for max breathability and warmth. Stretch panels along the sides and sleeves allow for freedom of movement, while a stretch fixed hood with halo adjust provides low-profile protection from the elements. This year, our Men’s Fernos Jacket earned recognition as the top pick in Outside’s 2025 Winter Gear Guide for Best in Men’s Active Insulation—in case you needed another reason to expand your kit.

PeakFill™ Active 40g Insulation, 50% Recycled Polyester, 50% 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.
