Outerwear ｜Men's Fernos Insulated Jacket

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.Features
