Bold, sporty and techy—just like our favorite mountain biking trails—this moisture-wicking top delivers dynamic performance while racking up style points from big ups to burly downs.

With the performance of a tech shirt and a splash of style, the Shifter Shirt rolls with anywhere from rowdy downhills to burly singletrack. Moisture wicking and feather light, this relaxed-fitting top stays cool on sweaty climbs and adds breathability from subtle underarm ventilating panels. Two-way stretch provides mobility on the twists and turns of the trail and UPF 50+ sun protection has you covered. For the final touches, a sunglasses loop on the chest pocket keeps shades accessible and a zippered pocket at the back hem stows small essentials.

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.
