The Cleanline 5/4 Hooded Chest Zip Wetsuit competes with the best wetsuit neoprene in the surf industry. The suit features premium Yamamoto #40 neoprene, made of limestone sourced from the mountain ranges of Japan. The Cleanline 5/4 Wetsuit keeps you warm and cozy like a cup of Joe but stretches like yoga pants in the gym. The durability coming from the fully taped seams, sealed cuffs, and critical taping is all time while still maximizing performance.
