Patagonia wetsuits feature high-quality Japanese super stretch neoprene that you won’t find in any other suit on the market. The interior consists of recycled poly fleece constructed as a grid to create dead air space and retain lots of warmth. An internal pullover style neck gasket blocks wind and prevents flushing at the zipper. Neoprene underarm panels are backed by nylon jersey on both sides for better stretch while paddling. All seams are single glued and blind stitched for durability; crotch seams are internally taped. Anatomical, compression molded knee pads are PVC-free for better durability and less environmental harm. Get into the shop today and check them out!!!
