The O'Neill Men's Pyrotech F. U. Z. E. FSW 32 Wetsuit has a F. U. Z. E. chest closure system that lets you quickly suit up so you can grab your board and paddle out toward that head high set before the others are even fully suited. Its unique front entry system features a code red zipper that uses a urethane coated zipper to keep water from entering at the chest while a double super seal neck offers wide adjustability and a watertight seal. To make sure the seams block water without restricting flexibility, the Pyrotech fluid seam weld construction uses a silicone based urethane seal applied to the opposite side of its glued and blindstitched seams. Super seal cuffs and plasma wrist and ankle seals also prevent flushing issues and seal out water. To further enhance comfort, the Pyrotech features 32mm Technobutter neoprene face fabric that's lighter, warmer, and more quick drying than the previous Technobutter neoprene. XDS Air Firewall insulation in the chest and back panels provides wind resistance and increases warmth without restricting mobility. And to make sure you can move the way you need to, a lumbar seamless design LSD uses a large panel in the rear area of the wetsuit to minimize water entry and maximize stretch. Krypto knee pads enhance durability and offer improved comfort, and an integrated key pocket ensures your car or hotel key doesn't end up on the ocean's floor.
