Various sizes wetsuits

At O’Neill you can find a wide range of wetsuits in various sizes. From an XS wetsuit to XL. Do you want to make sure you choose the right size? View our handy wetsuit size chart and discover your size. This also includes all other surf clothing and accessories. The wetsuits are available in thicknesses from 1 mm to 6mm. The thicker the neoprene, the warmer the wetsuit. Which thickness you need depends on the water temperature. You can find the temperature of your surf spot online. The thickness of a wetsuit is expressed in two numbers. For example 3/2mm. The number in front of the ‘/’ means the thickness of the neoprene on the back and stomach to keep you warm. The 2nd digit represents the number of mm on the arms and legs for optimal freedom of movement. In the overview below, you can see exactly which thickness fits which water temperature.
