Picture Organic Clothing Meta wetsuit 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 Picture Organic Clothing uses Aqua-A, a solvent-free water-based glue with no harmful chemicals. The Meta LS 2/2 zip-free long-sleeve version is designed for spring and summer sessions. The flatlock seams increase flexibility and freedom of movement. Its fuse cut and drain holes minimize water entry and maximize water draining. The Meta 2/2 also features the Thermal Standard lining to insulate and retain body heat. Enjoy this minimalist style for one great session after another!
