Our wetsuits are eco-awesome because our Ecofoam is levels above sustainable on the Eco-purity spectrum. They are awesome also because they are wetsuits of the highest performance on the market. They are warm, extra stretchy, exceptionally durable and comfortable! The Ecofoam is lighter than neoprene and approved by the United States Department of Agriculture (USDA) Bio Preferred® program. It is concocted from mixing natural rubber, plant oils and other natural compounds with a structural base that is the calcium carbonate extracted from oyster shells recycled from the seafood industry. How awesome is it to wear natural materials created by nature rather than some neoprene waste from the industrial petroleum refining complex?
