O'Neill Psycho One 5/4mm Chest Zip Wetsuit 2023 - Black

O'Neill Psycho One 5/4mm Chest Zip Men's Wetsuit 2023 in Black

The O'Neill Psycho One 5/4mm chest zip wetsuit has had a re-design this season with the inclusion of the Technobutter Firewall inside the suit. This new material is heat retaining thus keeping you warmer for longer in the water.

The Firewall is on the chest, back and legs in all the key areas to maintain body heat. So it nows now far warmer and with the Technobutter 3 neoprene on the arms, shoulders and calves it is also super flexible.

The Psycho One 5/4mm wetsuit is perfect for all-year-round use for those that feel the cold but is designed for the coldest winter months. The 5mm of neoprene and thermal lining ensures that you retain body heat for longer thus being superb in the UK's coldest months.

Another great thing is it can be used for all water sports and because it features Technobutter 3 neoprene it really feels like you are not wearing a wetsuit at all.

This year, it also uses Aqua Alpha solvent-free lamination and Eco Carbon Black in the neoprene making it a far more eco-friendly wetsuit than ever before.
