Technobutter 3
Pre-stretched innovative neoprene material by O'Neil. It features 30% less water absorption compared to other suit materials. It provides a high level of comfort during use, is lightweight and stretchy, while drying very quickly. The stretch factor is 160-180%.
Krypto Knee Pads
Ergonomic knee pads used in water sports wetsuits. The highly stretchable neoprene is abrasion resistant, provides comfort and increases the level of protection against damage.
TB3X Fully Taped Seams
The lightest 0.5 mm thick stretch neoprene tape applied over triple fully lined seams. Provides very good water blocking. This keeps the body dry and water sports comfortable.
F.U.Z.E.
F.U.Z.E., or Front Upper Zip Entry, is a zipper located on the front of the wetsuit at the top of the foam. Patented by the O'Neill brand, it ensures the comfort and maximum seal of the wetsuit.
TechnoButter 3X
Innovative technology in the manufacture of swimming foams from the O'Neill brand. The foam consists of an outer shell that protects the neoprene, offering the product high durability. A core with air cells gives the foam an incredible lightness. An inner layer with a special construction ensures fit and comfort. The result is a lightweight product with exceptional technical properties.
Aqua Alpha Solvent Free Neoprene Lamination
The layers are bonded using a water-based adhesive, without the use of solvents. This helps to preserve the material’s durability and flexibility. This approach also reduces the use of harsh chemicals in the production process.
