O'Neill 4/3 Wetsuits

Designed for water temperatures of about 12–16°C, O’Neill 4/3 wetsuits are perfect for cooler spring and autumn days, as well as mild winters. With 4mm neoprene in the body and 3mm in the arms and shoulders, they deliver reliable insulation without sacrificing too much flexibility. This balance makes them one of the most versatile thicknesses for UK surfers, bridging the gap between summer comfort and winter protection. Whether you’re after the dependable Reactor, the all-rounder Epic, or the premium Hyperfreak with superior stretch and comfort, the O’Neill 4/3 range has something for every surfer. If you want one wetsuit to cover most of the year, this is the sweet spot.
