GBS Seams
A technology for sewing and gluing seams, used in swimming foams, among other things. It involves not passing the needle through the entire material, so that no needle holes are created on one side of the suit. This minimises the risk of water ingress.
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.
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.
