When it came to wetsuits and wetsuit accessories, we wanted something warmer, more flexible, better fitting and tough enough to withstand extended use. Looking to what divers, sailors and fishermen had been using all these years to stay warm, in and on the ocean, we tried wool. For comfort and performance, we blend merino wool with polyester, and it’s this merino/polyester blend lining that gives our wetsuits their added warmth without added rubber. We make wetsuits in four weights for all water temperatures – R1® (warm), R2® (cool), R3® (cold), and R4® (frigid) – and in several cuts for men and women. Patagonia wetsuits are decidedly warmer than standard nylon-lined suits, but they also wear longer, dry faster and are made from post-consumer recycled polyester, merino wool softened without chlorine, and no PVC.
