The Fernos Insulated Pants are your answer to staying warm and moving freely when winter is in full swing. Designed for both high-output alpine missions and relaxed cold-weather outings, these versatile pants feature breathable PeakFill Active insulation wrapped in a soft, stretchy Relance Primeflex shell. They keep the chill out without overheating when you're working up a sweat on the trail, rink, or ski hill. With articulated knees, a gusseted fit, and jogger-style cuffs, they're built for full mobility and everyday comfort. Whether layering under a shell or wearing solo around town, the Fernos is a midlayer you'll never want to take off. | Stio Men's Fernos Insulated Pants
