With warm weather and wide-open countryside, the Portuguese coast feels like California before the crowds. The R1(R) Back-Zip Full Suit offers full-length comfort, keeping you out there until evening beckons with a caipirinha and a good night's sleep in the van. Handmade with ultra-flexible neoprene and a recycled polyester lining, wetsuit features include a flexible one-piece front panel, internal neck gasket to prevent water entry and an internal back flap to block wind. Flap closure at the neck allows for a stronger seal and increased comfort, and wrist and ankle cuffs are heat-pressed to reduce flushing. Anatomically engineered Supratex kneepads are flexible, durable and PVC-free. All critical seams and stress areas are secured with glue dots, 1cm bartacks and Melco(R) reinforcements.
