O'Neill Wetsuit Size Guide
Wetsuits are the most commonly used dive suits, with a general thickness ranging from 1.5mm to 10mm. Coldwater will be isolated by the clothes, will not penetrate again, and will quickly become heated by body heat conduction. Wetsuits are usually made of foam neoprene. The insulating properties of the wetsuit depend on the gas-encapsulating effect of the foam material to reduce heat transfer; the air bubbles also give the suit a low density, providing buoyancy in the water.
If you're looking for a well-fitting wetsuit for your next diving or surfing, the O'Neill chain store is the place to go. Wetsuits have been the lifeblood of O'Neil for more than 50 years of brand development. The choice of a wetsuit is related to your safety during water sports. We have size charts available below; please take them with a grain of salt.
