We are proud to introduce our all-new Onsen line of wetsuits, constructed with 100% Yamamoto #40 neoprene. Protecting and preserving our oceans, seas, and rivers—our playground, our livelihoods, our sacred spaces—drives our relentless efforts to develop and build our wetsuits with materials that are uncompromising in sustainability, lifespan, and performance.
And that commitment has led us to Yamamoto, the global leader in sustainable limestone-based neoprene. The Yamamoto #40 neoprene used in our Onsen wetsuits is significant for several reasons, both in terms of the environment and performance.
