Constructed with superlight TechnoButter 3, the O'Neill Hyperfreak 2mm Chest-Zip Long-Sleeve Spring Suit gives us a light, flexible wetsuit that suits our cool-to-warm weather surfing needs. Designed with stretchy, wickedly comfortable, insulated 2mm Technobutter 3 and TB3X neoprene, the Hyperfreak keeps the chill at bay so we can focus on more important things, like surfing. Its 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.
