O'Neill Hyperfreak Fire 3/2mm+ Chest Zip Fullsuit
The O'Neill Hyperfreak Fire is built for surfers chasing extreme warmth without giving up flexibility, and this 3/2mm plus chest zip version is part of the range O'Neill designed around all new, sustainable, heat recirculating TechnoButter 4 materials. The plus in the thickness name means an extra 0.5mm has been added for even more warmth.

Who This Fullsuit Is For
This suit fits surfers in South Florida who paddle out during the coolest stretches of the season, including early dawn patrol sessions, and want maximum warmth without sacrificing the flexibility needed to duck dive and paddle for extended periods. It also suits anyone spending long hours in the water on cooler days, since the segmented wrist and ankle seals and anti flush barrier are built to keep cold water from seeping in at the extremities.
Fit, Wear, and Care
A cold water fullsuit like this should fit close to the body with the tapered cuffs sealing snugly at the wrists and ankles. Rinse thoroughly in fresh water after each session to protect the Fluid Seam welds, dry away from direct sunlight, and store flat or on a wide hanger. Because this suit uses premium taped and welded seam construction, avoid harsh folding that could stress the seams over time.
