Refined over years of rigorous field-testing, the new Shearwater 5mm is our warmest, most technically advanced cold water wetsuit to date. Completely redesigned from the ground up, our men's Shearwater wetsuits feature a brand new U-Zip for ease of entry and exit, as well as enhanced S-Seam technology for our best fit and most flexible suit yet. Warm, comfortable and, as always, made with natural rubber, they’re built to keep you in the lineup for longer (85% natural rubber (OCENA®)/15% synthetic rubber by polymer content). Cold water doesn’t compromise, so neither do we. Suitable for sea temperatures of 7-11°C/45-52°F.
