Key features
What makes it work.
360° Anti-Flush Barrier
The 360° barrier helps limit flushing through the suit, while drain holes allow excess water to escape.
Minimal Seam Design
Fewer seams help reduce restriction through the suit, supporting a lighter feel and greater freedom of movement.
Plus Warmth
An additional 0.5mm of thickness is used to provide extra warmth for colder conditions.
F.U.Z.E. Entry
The front upper zip entry is designed for a close, secure seal while keeping the upper body flexible.
Glued & Blindstitched Seams
Glued and blindstitched seam construction helps limit water entry while maintaining flexibility and comfort.
TechnoButter 3X
TechnoButter 3X provides lightweight stretch through high-movement areas to support unrestricted paddling and turns.
Sustainability
Built with less impact.
-
Aqua Alpha Lamination
Bonds the linings without harsh solvent-based adhesives, offering a more environmentally conscious approach to wetsuit construction.
Fit & sizing
Find your right fit.
Check the fit notes, size guide or dimensions before ordering. Sizing can vary by brand, style and intended use.
