The Flexskin neoprene 1.5 Hybrid is part of our line of eco-friendly surf tops.  This top is 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 we use Aqua-A™, a solvent-free water-based glue with no harmful chemicals. This top provides incredible freedom of movement in the water through its body-mapping construction, including zones of lycra. It also features chafe-free seams for extra comfort.
