Overview

As cozy and versatile as your favorite puffy jacket, this lightweight slip serves up soft, fleece-lined warmth you can sink your feet into.

Your feet deserve every comfort after a big day in the mountains or being stuffed into ski boots—and our mountain slip provides. Lightly insulated to keep out the cold, toes sink deliciously into a plush fleece lining and extra cushy footbed. A quilted upper maintains appearances and resists light precip when venturing out, while the fold-down heel easily switches in and out of slipper mode. The soft EVA foam midsole cushions your steps, while traction rubber built into the outsole’s high-wear spots under the ball of the foot and heel grips slick surfaces and adds durability. Abrasion-resistant fabric on the heel and toe cap minimizes wear and tear.

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.

Materials

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.

Stio Second Turn®

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.
