Long runs and race days deserve a tight built for endurance. Our athletic design finds inner strength from a nylon/spandex fabric that is tough enough to withstand brush, formulated to enhance wicking and treated to reduce odor whether grinding out a tough training run or sweating through a sufferfest.
Fortis™, built with stretch interlock technology, is an extremely flexible nylon/spandex fabric. Its sueded finish offers a soft handfeel, while moisture management and an anti-microbial treatment improve comfort and reduce odor during any active pursuit.
We completely offset the footprint of each order through our commitment to being climate neutral. As part of our mission we value being good caretakers of the mountain life and protecting the places where we play.
We are committed to building garments that are durable, timeless and continue to perform season after season. Over 50% of our product line incorporates preferred materials, which include organic cotton, recycled materials and responsibly-sourced down. We are committed to growing our preferred materials usage to 75% by 2025.
We believe a circular commerce system will design out waste and pollution, allowing for used clothing to be renewed and put back into use. Stio Second Turn™️ is our gear renewal program that allows customers to trade in and shop used apparel.
