Sure So-Cal is cool, but have you ever gotten pitted riding a deserted beach break on the Oregon coast in January? The O'Neill 4/3+ Psycho Tech Chest Zip Wetsuit is the cold water suit you need to expand your horizons beyond your usual surf spots. Stitch-less seam technology and TechnoButter 3 neoprene make for unrivaled flexibility, and say goodbye to cold water flushing; F.U.Z.E. chest closure and Z.E.N. back closure systems incorporate anti-flush barriers with drain holes to keep you warmer for longer.
TechnoButter 3 [Arms, Shoulders, Shins, Calves] – O'Neills exclusive, maximum stretch, hydrophobic neoprene with featherlight ENVY foam rubber core. Ultimate warmth and comfort, built to last.
TechnoButter 3 Air-Firewall Smoothskin [Chest & Back] – The most advanced insulative neoprene available with even more stretch than before. Trapped air technology with quick dry and wind proof properties. Psychotically warm.
TechnoButter 3 Firewall [Thighs & Butt] – Light, insulating neoprene foam core with heat retaining thermal interior layer and quick dry properties. Stretchier than ever before.
