About O'Neill
In the water
Wetsuits are the brand's foundation, built for warmth and flexibility. For UK seas, O'Neill suggests 5/4mm suits in winter, 4/3mm for spring and autumn, and 3/2mm in summer. Boardshorts, rash vests and swimwear cover warmer days. Wetsuits come with a one-year warranty against manufacturing defects, which applies in full once you register the suit online.
Look after a wetsuit by rinsing it in fresh water after every session. Dry it inside out, out of direct sun, and hang it or roll it loosely rather than folding it.
On the slopes and around town
Snow gear includes insulated jackets, waterproof trousers and base layers for skiing and snowboarding. Casual clothing covers t-shirts, hoodies and dresses, with hats, bags and sunglasses as accessories.
