O'Neill Hyperfreak Chest Zip Wetsuit

The 3/2mm thickness is designed for mild to warm water conditions, typically ranging from 58°F to 68°F (14°C to 20°C). It provides enough insulation for cooler mornings without overheating you once the sun comes out.

The F.U.Z.E. (Front Upper Zip Entry) system offers significantly more flexibility across the back panel, which is crucial for paddling efficiency. While back zips are generally easier to get into, this chest entry creates a better seal against water flushing and feels less restrictive during movement.

TechnoButter 3 is O'Neill's proprietary neoprene that is exceptionally lightweight and stretchy, while the 3X version is even lighter and more flexible. This combination allows for a full range of motion that feels more like wearing a rash guard than a traditional wetsuit.

Not at all. The TB3X tape is designed to be low-profile and highly elastic, so it reinforces the seams against leaks without creating stiff, bulky areas that could restrict your movement or cause chafing.

This feature acts as a secondary seal inside the chest entry to prevent water from entering the suit if you take a heavy wipeout. The drain holes ensure that any water that does get past the zipper is quickly flushed out, keeping the suit lightweight.
