It has been tested and is approved by the United States Department of Agriculture (USDA) Bio Preferred program as a USDA Biobased product. Greenprene is formulated from deproteinized natural insulating foam along with other natural additives such as sugar cane, plant oils and oyster shells. The result is a sustainable Bio Based insulating foam that is ultra-soft, stretchy, durable and light weight. Greenprene wetsuits will allow you to move freely without restriction while keeping you warm and comfortable in the most demanding conditions. "
