Why We Use Yamamoto Limestone-Based Rubber

Feb 15, 2025

Because we're dedicated to representing real-deal excellence. Aka: The best wetsuits, like parachutes, must work — every time. And like winning Olympic Track & Field gold medals, stronger is always better. 

Simply put: We believe that the Yamamoto Corporation in Osaka, Japan produces the world's best and most durable rubber. And we exclusively use the pinnacle offering of their most advanced materials. Aka what we call: OG Optimum Technology.

+ Limestone-based -- as opposed to being made from petroleum

+ Titanium-coated & laminated to the finest hydrophobic 4-way stretch & pill-proof nylon on the market (markedly increasing responsiveness & overall product lifespan)

+ 99% water impermeable compared to the standard 65% via oil-derived neoprene

For OG Optimum Technology, the functional superiority is real -- and so is the perfectly uniform microcell structure that's shaped like tiny hexagons (as opposed to how the cell structure of oil-based neoprene looks and functions more like your kitchen sponge).  

Point being: Yamamoto materials produce a lighter, warmer & longer-lasting wetsuit -- because of the water that your wetsuit doesn't absorb. Moreover, we are also confident that the most ecologically sound wetsuit (or car or whatever you purchase) is the one that lasts the longest while functioning at the highest level. 

To slow down human consumption and advocate for the customer's return on investment, a premium and sustainable product must include functional performance that is both legitimate and durable. 

And we are proud to say that our job is to represent all of the above -- with the greatest integrity, sincerity and execution. Going strong -- since Day One. Cheers & Enjoy
