O'Neill's Chest Zip Entry Wetsuit is the most unique, lightest and fully sealed wetsuit on the market. This advanced technology allows you to preform at the highest level with materials so comfortable and light you'd swear you were surfing naked.
The Hyperfreak series features the exclusive TechnoButter 3 & TB3X material, now lighter and butterier than ever. 20% lighter and 30% less water absorption.
This season an additional 0.5mm of neoprene is added to the wetsuit = extra warmth!
- FUZE Entry System: O'Neill's exclusive FUZE (Front Upper Zip Entry) system offers a fresh alternative. Use the same free-floating zipper technology as our patented ZEN zipper. The FUZE closure keeps you dry and allows unrestricted flexibility.
- Technobutter 3 & TB3X Neoprene: O'Neill's exclusive new improved hydrophobic stretch neoprene with featherlight ENVY foam rubber core. Ultimate, flexibility, warmth and comfort. Combined with Technobutter 3X, the lightest, most flexible and softest material ever made.
- Glued, blind stitched and glued seams: Soft and durable neoprene seam tape. 0.5mm split neoprene applied to triple taped seams to seal out water and keep you dry and relaxed.
- Double Superseal neck: A toasty warm two-layer design with a 360° smooth interior lining, wide adjustability and a secure closure. Fully adjustable and waterproof.
- Strategic Seamless Paddling Zones: An ergonomic, seamless underarm panel that allows unrestricted movement and prevents rashes. Flexible and unique design with minimal seam placement for greater comfort.
- Crypto knee pads: abrasion resistant, highly stretchy Neoprene panel with ergonomic design for comfortable durability. The flexible and unique design utilizes an extended knee pad for added durability.
- External key pocket with loop: Abrasion-resistant, high-stretch neoprene panel with ergonomic design for comfortable durability. Located along the inseam of the legs. Constructed from Fluid Seam Weld and UltraFlex DS neoprene, this key pocket provides added strength, easy access and complete security.
Rinse after use
Rinse your wetsuit with fresh water after every session – whether in the sea or a lake. This removes salt, chlorine, and other residues that can make the material brittle.
Drying correctly
Always hang the suit inside out, as the inner lining retains more water. Use a wide hanger or the trouser bar to prevent pressure marks on the shoulders. It is best to let it dry in the shade in a breezy spot – not in direct sunlight.
Do not put in the washing machine!
Use a special wetsuit shampoo instead (e.g., Slosh or Rip Curl's Piss Off) for a thorough cleaning.
Storage
Store the suit dry and on a wide hanger – do not fold or crumple it, as this can damage the neoprene.
