O'Neill Hyperfreak 4/3+mm Men's Chest Zip Wetsuit 2026 - Black

O'Neill Hyperfreak 4/3+mm Mens Chest Zip Wetsuit in Black

The O'Neill Hyperfreak 4/3+mm Men's Chest Zip Wetsuit has been upgraded to now include fully taped seams to ensure no water intake while maintaining flexibility. The "+" relates to an extra 0.5mm of Technobutter 3 neoprene on the body of the suit and an extra 0.5mm of 3X neoprene on the arms and shoulders, giving you additional warmth while still maintaining incredible flexibility. This is a brilliant suit for those wanting to be in the water from April until January, making it an excellent all-year-round choice.

The new Technobutter 3 and 3X neoprene genuinely feels like an item of clothing to the touch, and is some of the most flexible neoprene available. Once it's on, it delivers a level of comfort that stands apart, and the technology behind it goes well beyond feel alone. The neoprene is pre-stretched, so it holds its shape over time, all while remaining light, flexible, and soft. Technobutter 3 is a standout material, and on the inner part of the suit you'll find drainage lines designed to clear water from the suit while you're out in it, helping the whole thing perform better through a session.

The chest zip entry uses O'Neill's Fuze Closure System, paired with a minimal seam design for genuinely unrestricted movement. A 360-degree barrier with drain holes helps prevent water intake, while a double seal neck adds comfort and warmth around the collar. Together, these features make the Hyperfreak 4/3+mm a genuine step forward in wetsuit performance and comfort.
