TB4 Firewall utilises recycled graphene fibres at a thicker pile. As your body heat warms the graphene fibres, they return heat back into your body.

TB4, our award-winning wetsuit technology, introduces recycled yarns infused with graphene for increased flexibility and heat retention.

TB4X technology features graphene fibres lining the jersey allowing for incredible stretch with added strength and warmth retention.

This seam construction utilises a non-chafing, high-grade urethane applied in liquid form to the outside of a glued and blindstitched seam, completely blocking out water without restricting flexibility.

The F.U.Z.E. closure is O'Neill's exclusive chest zip system. It uses a free-floating zipper technology, keeps you dry and allows unrestricted flexibility.
