Lightweight, stretchy, breathable insulation for active warmth and performance.
Product Description
Fernos 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.

Stewardship
Partnerships
As caretakers of the mountain life, we recognize our responsibility to support organizations and people who share our vision to drive positive change for people and the planet. We’re proud to partner with some tremendous organizations in their missions to responsibly advance outdoor recreation and protect our wild surroundings.
We are committed to building garments that are durable, timeless and continue to perform season after season. After years of research, testing and product development, in 2024 we completely removed PFAS from all of our newly developed products. We remain committed to growing our Preferred Materials usage, which includes organic cotton, recycled materials and responsibly-sourced down and wool, to 75% by the end of 2025.
Our apparel is built to last. As a part of our efforts to reduce waste and keep more gear in the mountains where it belongs, our home-grown gear renewal program allows previously-used items to be traded in, cleaned, repaired and circulated back into use.
