Patagonia wetsuits feature high-quality Japanese superstretch neoprene that you won't find in any other suit on the market. Smooth skin coating on the torso and back reduce evaporative cooling in windy conditions. The interior consists of recycled polyester laminated to chlorine-free merino wool. It's constructed as a grid to create dead air space and retain lots of warmth. The wool is fast drying and reduces odor. 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. Recycled polyester jersey outside the seat and legs increases durability with less environmental impact. All seams are triple glued and blindstitched for durability; crotch seams are internally taped. Anatomical, compression molded kneepads are PVC-free for better durability and less environmental harm.
Patagonia does wetsuits differently. They stand behind every suit with a lifetime warranty (does not cover wear and tear, of course.)
