Not all mountain weather requires a stiff storm shell. Made as a more flexible alternative to technical overkill, our Millibar harnesses GORE-TEX INFINIUM™ WINDSTOPPER® technology to block wind, shed weather and stretch liberally — adeptly walking the ridgeline between protection and liberation with alpine style. Paired with a brushed grid backer for light warmth and underarm stretch panels for breathability, it maintains a comfortable core for alpine pursuits.

GORE-TEX INFINIUM™ 3L WINDSTOPPER® is a fully windproof softshell fabric with a stretch construction that increases range of motion.

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.

The charm in gravity.
When winter calls, we answer. It’s what draws us back—the feeling that lifts us, shapes us, fuels the fire inside. It’s in the cadence of the turn, the clean lines between aspen and fir. At Stio, we serve all those who share in the pursuit, because it's never not worth it. Join us. Chase bliss.
Made for mavens.
At Stio, everything we create is engineered to work without fail in the mountains; the Women’s Objective Pro Collection brings our obsession with performance to an all-new women's line. Breathable, beautiful and badass, Objective performs at the highest level from the chairlift to the Haute Route in a durable design to be trusted day-in and skin-out. Which is to say, it’s built like a Stio … for every woman.
Alaskan Exit Strategy
No adventure in Alaska is a gimme. On a glacial ski traverse outside Anchorage, Stio Mountain Athlete Nicole Cordingley learned that even the best-laid plans require thinking on your feet—or skis—in The Last Frontier.
