We exist to push the performance limits of sustainable materials, creating a future where the world's highest-performing gear doesn't harm the environment.
Indersity's story begins with Sam Digiambattista, a lifelong skier who discovered the extensive use of PFAS in outerwear early on. Sam shared what he had learned with the ski community around him to see if others felt as strongly about the issue as he did. To his expectations, the response was unanimous; skiers hated that PFAS chemicals were in their outerwear. So, Sam decided he would work towards a solution, and thus Indersity was born.
Sam's goal was ambitious. And when you learn that Sam had no background in textile engineering, it might sound even crazier. However, Sam never set out to be a technical engineer lead; That wasn't his skillset. Sam's background is entrepreneurship, from starting small businesses himself to regularly spending time at NYU Stern and surrounding himself with business owners his whole life. He focused on the steps the business needed to take, who needed to be involved, and how to find those people and align them with our vision in order for Indersity to not only develop a solution but actually bring one to market. His vision, deep understanding of the customers' needs, adaptability, and eagerness to outwork everyone are what fueled Indersity.
Indersity's journey kicked off with Sam approaching engineers and labs around the country in search of the people and resources needed for Indersity to pursue the development of a new material. Sam found a handful of labs that had actually made early-stage progress towards a top-performing PFAS-Free* material, but left their projects on the back burner because there weren't any interested brands. At the time, hardly anyone was aware of PFAS, and the big brand PFAS shell materials sold extremely well; this is why brands showed no interest. This was huge for Indersity. Sam happened to be the only one approaching these labs and engineers who was committed to bringing a top-performing PFAS-free* solution to the outerwear market, which not only allowed him to partner with these groups that shared his vision and had already made early-stage progress towards a solution, but also to secure exclusivity agreements on the materials Indersity developed with them.
*No intentionally added per- and polyfluorinated substances.
Now that Sam found capable partners with proof that a solution is possible, Sam raised $50,000 from family members to go in on Indersity. After a year of developing and testing new solutions, we developed a three-layer rugged shell material that has a 40,000mm waterproof rating, a 30,000g mvtr rating, and is PFAS-Free*.
*No intentionally added per- and polyfluorinated substances.
The next step was to create outerwear. Before there was the Stratos Storm Shell, Indersity created the 40/30 shell, named after InderShield™'s performance ratings. We collaborated with a few athletes from Utah and Switzerland to refine the fit and function of our first shell. Our goal was to blend backcountry functionality with a freeride style to create a shell that had it all: performance, functionality, and style.
In the 2024/2025 season, we beta-launched the 40/30 shell to competitive freeride athletes. This was our first shell, and we were seeking out as much raw feedback as possible. So we went straight to the skiers who would put our shell through the ringer in the freeride and backcountry environments the shell is meant for.
We also launched a small batch of shells on our website.
The launch was a great success. We found competitive freeride athletes across North America who loved our mission, giving us invaluable feedback on our gear and spreading the word to their home mountain communities. In addition to that, we sold out on our website through purely organic reach.
Now, thanks to the competitive freeride skiers' early support and invaluable feedback to our company, we've sponsored them all so that we can continue creating and testing gear with those who push it to the limits, and continue spreading the word through local communities.
Indersity's development of InderShield™ and our grassroots marketing success caught the attention of a handful of investors from Sun Valley, Silicon Valley, and New York City. Sam raised money from investors to fund Indersity's expansion and begin the development of a lightweight version of InderShield™.
After working with over 40 freeride athletes who wore our shell during the 24'/25' season, we are now launching our 25'/26' winter line with our most durable and most functional design yet. Our shellwear has gone through thousands of hours of testing by dozens of hardcore skiers and mountaineers for us to perfect every inch of our 25'/26' line.
I was genuinely blown away with this shell. I had it all winter and it never let me down. All season I kept finding new reasons to love it and all of its features. I’m so happy to be riding in the best the market has to offer while staying environmentally friendly. The performance is unmatched and quality is on point.

This jacket has been a dream to ride. I’ve stayed warm and dry throughout the whole year with it even on the nastiest days. There’s also something reassuring about knowing you’re not riding gear that harms the environment. Would 100% recommend for anyone that skis hard all year long.

I’ve worn Indersity for a year now and love every piece of it. I love knowing that I am wearing something that isn’t harming our environment and keeps it cleaner but also like wearing something that keeps me dry and warm no matter the conditions. I really like the breathability and waterproofness.

Best quality jacket I’ve worn in my life. Super waterproof with out using forever chemicals that ruin the environment. They do this while still keeping perfect breathability and fit.

Can't recommend this jacket enough! 40,000mm and 30,000 g/m2 is literally the best in the world and it shows. I also care a lot about the environment and this being PFAS Free makes it that much better. This jacket is clearly designed by skiers with the pocket sizes and placement, the big vents and the fit. This is by far the best shell I've ever worn having tested it out on a rainy day and while it was snowing

This jacket has been incredible all season. InderShield performance is no joke, I've been comfortable all season and haven't gotten wet once. The jacket design is also incredible, it's a perfect balance of backcountry functionality and style. Truly an incredible product and exciting new brand to follow.

The waterproofing on this shell is incredible. I came across Indersity on Instagram and was skeptical with it being a new brand. My last shell broke on me and I decided to take the risk and see what the 40k/30k performance was all about. I've been super impressed every day using this shell. The material's performance is the best I've ever experienced and I've used goretex pro for a while until ...
