ONeill Mens Hyperfreak Y2K 2mm CZ SS Spring Suit Wetsuit is built for surfers who want high-end stretch, lightweight warmth and unrestricted paddle freedom. Made with a performance blend of TB3X and TB3 neoprene, this 2mm short sleeve spring suit delivers a barely-there feel while still offering reliable coverage for warm-water surf sessions. The chest zip entry, sealed GBS and taped seams, and minimal seam design work together to improve comfort, flexibility and durability in the water.
