That’s why we craft our wetsuits with the planet in mind, using cutting-edge materials like OCENA® rubber aka Neoprene-free foam. Developed from FSC-certified natural rubber, oyster shell powder, and plant-based oils, OCENA® represents the most sustainable alternative to traditional neoprene — without sacrificing the performance and durability that Matuse is known for.

Now, OCENA® is not only more environmentally friendly — it’s also more flexible than ever before, lighter both in and out of the water, and engineered to dry faster. These improvements mean even greater comfort, mobility, and performance in every session.

Backed by over four decades of Sheico’s rubber foaming expertise, OCENA® rubber delivers exceptional elasticity and resilience, all while significantly reducing environmental impact. It’s the perfect match for Matuse’s mission: to make products Ichiban, the best!
