O'NEILL HYPERFREAK 4/3
Benefits from TB3 construction throughout the body and features the exceptional TechnoButter 3X on the shoulders and arms. And that's a good thing, because that is exactly where you need maximum flex for more efficient and less tiring movements. This proprietary neoprene offers a stretch of 180 to 220% - incredible values.
The glued seams are coated on the inside with TB3X tape, which ensures comfort, flexibility, water resistance, and seam strength.
A 0.5 mm thick layer of neoprene has been added for those who are sensitive to the cold.
The front-zip entry system, or chest zip (F.U.Z.E. system at O'Neill), frees the back panel from any fasteners, giving you even more flexibility and less fatigue when paddling. Additionally, water penetration is extremely limited.
Features:
- TechnoButter 3X neoprene shoulders and arms
- TechnoButter 3 neoprene on the body
- F.U.Z.E. Closure (chest zip)
- Minimal Seam Design with TB3X tape
- Limestone neoprene based on limestone derivatives
- Water-based adhesives
If you are between two sizes according to the size chart, you should generally choose the smaller of the two options. Wetsuits must fit very snugly when trying them on for the first time. The material will stretch slightly in the first few days, and your suit's warming function is only optimal if it fits skin-tight.
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.
