The Men's Patagonia Yulex Regulator Lite Front-Zip Long-Sleeved Wetsuit Top is a lightweight top for surfing. The Yulex natural rubber and chlorine-free synthetic rubber blend is stretchy and protective, for taking on cool waters and abrasion. A center front zip with noncorroding Riri zippers provides a better seal and extends the suits lifespan. The zipper can be repaired or replaced, and all seams are triple-glued and blindstitched internally, plus spot-taped at high-stress areas. The fused-edge waist hem offers a lower profile and lies comfortably against the skin, so you can focus on the waves, water, and your board.
