Stewardship

A commitment to protecting the places where we play.

We are stewards
of the mountain life.

We choose the mountain life, and we're committed to protecting the places where we play, and to our journey in stewardship. Every year we strive to do better—use better materials, work with committed partners and create the best possible working environment. We regularly take stock of and share out our progress. This transparency with our community keeps us moving forward. Follow along as we put in the work and do our part to be stewards of the mountain life.

“At Stio we are committed to doing the right thing, bringing people closer to the mountains while building a business designed to last."

—Stephen Sullivan, Founder/CEO

We choose better materials for the planet.

Every choice we make in the mountains matters, and the same goes for our materials. Each season we strive to adopt more recycled and responsibly-sourced materials, progressing toward our goal of adopting 75% Preferred Materials across the line. In 2025 we saw a slight dip in Preferred Materials as a percentage of overall volume, but held steady on responsible down and began accounting for the Responsible Wool Standard. Looking ahead, we expect meaningful gains in 2026 as we integrate recycled-content NetPlus® across key styles and transition several high-volume lining materials to preferred options.

We verify that, to the best of our knowledge, the products manufactured by Stio and under the name Stio, materially comply with California Proposition 65.

We partner for positive change.

We proudly partner with like-minded organizations that share our values to contribute to our communities and protect the places where we play, including Protect Our Winters, The Change Climate Project and Mountain Town 2030. Last year we raised over $10,000 for POW during our first annual Season Kickoff Party hosted at Stio Mountain Studios across the U.S.

Measuring Our Impact
The Climate Label certification recognizes Stio's commitment to reducing carbon emissions across the company and throughout our supply chain, as well as our investments in less carbon-intensive Preferred Materials and contributions to climate-impact advocacy groups.

Our most recent 2024 carbon footprint totaled 11,413 metric tons of CO₂e., down roughly 25% from our 2020 benchmark. Over 97% of these emissions come from sources like raw materials, manufacturing, shipping and our printed catalog.

Our 2024 carbon intensity—emissions per dollar of revenue—was 0.15 kg CO₂e/$, continuing a steady decline over the past 5 years. This represents a 68% reduction in carbon intensity since 2020. Key drivers continue to be our preferred materials platform, sending fewer printed catalogs and using more sea rather than air shipments for imported products.

We are PFAS-free.

Newly developed Stio products are completely free of PFAS—also known as forever chemicals. We're proud to offer trusted waterproof layers that still meet our high standards for protection, as we continue striving for the most responsible practices across our line.

We work for local impact.

We think outside is the best side and you can't improve on nature. It's good for the mind, body and soul—and we believe everyone deserves access to it, regardless of race, gender, beliefs, background or ability. Inclusion isn't just something we strive for at Stio; we actively work toward it in our local and national communities.

In 2025, Stio gave back $184,624 across 196 nonprofit partners. Our giving ranged from grassroots community organizations to national advocacy groups, with product and cash donations supporting causes close to our mountain community.

A special highlight includes our longtime partnership with Coombs Outdoors, where we contributed 420 units of outdoor apparel to underserved youth valued at over $108,000.

We give gear a second turn.

We build gear to last, and our home-grown gear renewal program helps keep our enduring apparel out in the mountains where it belongs. Through Stio Second Turn® customers can trade in pre-loved Stio items to be cleaned, renewed and given a second turn in the mountains through our partnership with Tersus Solutions.

*You may notice lower numbers than in 2024 due to fewer items being processed and lighter overall weight of garments traded in.
