The O'Neill Men's Hyperfreak F. U. Z. E. SS Full Wetsuit gives you a light, flexible, short sleeve wetsuit that suits your cool to warm weather surfing needs. Designed with stretchy, wickedly comfortable, insulated 2mm Technobutter neoprene, the Hyperfreak keeps the chill at bay so you can focus on more important things, like surfing. Glued and blindstitched seam construction and taped critical and reinforced seam junctions eliminate leakage issues while the Hyperfreak's minimal seam design provides insane flexibility, fit, and warmth due to less seams. Strategic paddle zones, a contortionist seamless shoulder design, and Sidewinder S Curve seams supply unrestricted movement so you don't feel bogged down while you paddle. The designers at O'Neill also gave the Hyperfreak a Lumbar seamless design LSD which uses a large panel in the rear area of the wetsuit to minimize water entry and maximize stretch. A F. U. Z. E. chest entry system with a double super seal neck offers easy on and off, minimal bulk, wide adjustability, and 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.
