The 3mm Equation Gloves are the perfect eco-friendly surf gloves to keep you warm in cold water. They are made with the latest Eicoprene technology, a non-petroleum based synthetic foam derived from a mix of oyster shell powder, limestone, and recycled tires. To laminate the recycled polyester lining Pictue Organic Clothing uses Aqua-A, a solvent-free water-based glue with no harmful chemicals. The gloves have glideskin cuffs to minimize water entry, and silicon-covered palms for a non-slip grip. They also feature glued, blind-stitched, fully-taped seams (GBS) for ample stretch when in the water and dry quickly between two sessions.
