At Nixsa, every wetsuit begins with a commitment to performance, comfort, and environmental responsibility. That’s why we choose Yamamoto Japanese limestone rubber—a premium neoprene alternative renowned for its quality and sustainability.

Yamamoto rubber originates in Japan, where the limestone used in its production is extracted from deep, ancient quarries. Unlike petroleum-based neoprene, which relies on finite fossil fuels, limestone is an abundant natural resource. The Yamamoto process transforms this raw limestone into chloroprene rubber chips through a carefully controlled chemical process. These chips are then expanded using nitrogen cells, creating an ultra-light, closed-cell structure that traps heat, repels water, and offers unmatched flexibility.

This meticulous Japanese manufacturing method is what makes Yamamoto rubber unique. Its closed-cell composition is 99.7% impermeable, absorbing significantly less water than standard neoprene. This means your wetsuit stays lighter, dries faster, and keeps you warmer for longer. The elasticity of Yamamoto rubber also delivers a second-skin fit, reducing resistance and allowing for full, unrestricted movement in the water.

Choosing Yamamoto isn’t just about performance—it’s also about reducing our environmental footprint. Limestone-based neoprene has a lower carbon impact, requires less energy to produce, and results in a wetsuit that lasts longer, meaning less waste over time. Every panel in a Nixsa wetsuit is cut and assembled to maximise these benefits, ensuring the perfect blend of warmth, durability, and sustainability. From Cornwall’s icy winter swells to warm summer surf abroad, Nixsa wetsuits made from Yamamoto Japanese limestone rubber keep you in your element—delivering world-class performance while respecting the oceans we love.
