SE4:EP12 - Sandy Flint: Stio on Sustainability

Over the past few years you’ve probably noticed the brand Stio on the slopes. Born in the Mountain West, the company has become known for its extensive colors and a serious focus on technical materials that are sustainable. Last Chair did a visit with Stio Senior Materials Manager Sandy Flint to learn more about its products, which are both revolutionizing outdoor clothing performance and utilizing technology which is more friendly to the environment we all love so much.

Stio was founded in 2011 by Mountain West native Stephen Sullivan, who had previously started the Cloudveil brand. Stio quickly became known for its focus on core technical apparel, fun colorways and direct-to-consumer sales. Today, the company has its own Stio Mountain Studios at major resorts across the west, including Utah on Park City’s historic Main Street.

Flint grew up in the Northeast, skiing around New England and taking family trips out west. “It was the mountains I loved – being able to hike, raft and ski.” He went to college in Colorado, then moved to Utah, teaching skiing at Solitude. With a degree in engineering and a background in art, he found his way into a graduate program studying fiber science and apparel design at Cornell. The combination of those technical skills with his passion for art landed him at Stio.

What you quickly learn in talking to Flint is his passion for sustainability, and knowledge of how to find that pathway. Most of all, you learn that he’s not alone, working at a company focused on the future. Today, preferred materials comprise 48% of Stio's collection and the brand has a goal to meet 75% by 2025.

We also learn that sustainability is about more than just raw materials. It’s an accounting of everything the company does from travel to manufacturing to shipping to recycling. Everyone in the company is accountable!

In this episode of Last Chair, Flint dives deep into the science and history of membranes and other materials. One of the most notable transitions is the evolution from the polytetrafluoroethylene (PTFE)-based Gore-Tex of the past to environmentally-friendly ePE membrane that is per- and poly-fluorinated chemical (PFC) free.
