The Stio Men's Fernos Insulated Jacket didn’t win Outside’s Editor’s Choice award by playing it safe. This member of the Fernos Collection provides a streamlined solution for mountain athletes seeking warmth and technical performance on the trail, with everyday comfort to wear all season. Synthetic PeakFill® Active insulation offers greater stretch, faster recovery and quicker drying times than traditional lofted insulation due to the fiber’s unique spiral structure. We mapped it for more warmth in your core and less in your arms, making it an ideal training partner in cold conditions. The stretchy outer face’s PFAS-free water-repellent finish resists light precip and speeds up drying times, while offering a soft handfeel. Zippered chest and handwarmer pockets stash what you need and an adjustable hem seals out cold updrafts.
