Built with ultra-light materials and advanced neoprene technology, it’s one of O’Neill’s most flexible winter suits while still offering serious insulation for colder sessions.

Engineered with TechnoButter 3 and TechnoButter 3X neoprene, it reduces weight and water absorption while maintaining excellent stretch and fast-drying performance. The added “+” thickness provides extra warmth where it’s needed most, making it ideal for UK winter surf conditions.
