GEOFLEX: A limestone-based rubber that is engineered to provide maximum flexibility for an unparalleled fit and is kinder to mother nature. HYDRASILK: The next generation nylon, is a silky-smooth material that creates a hydrophobic (rejects H20) barrier. This barrier minimizes how much water is absorbed into its rubber core and protects against wind, keeping you warmer and drier, while making the suit lighter and longer-lasting. Plus it makes you feel all buttery inside. SUSTAINABILITY: Each Geoflex wetsuit is Fair Trade certified, and contains reclaimed rubber tires, recycled neoprene, and water-based glue (solvent-free).
