TechnoButter 3 – O'Neill's exclusive, maximum stretch, hydrophobic neoprene features 3 layers of material. The maximum stretch hydrophobic jersey exterior stays flexible and dry by shedding water for the lifetime of the product. An Envy foam rubber core features featherlight warmth through the use of a microscopic air-cell rubber formula that increases the insulation factor by decreasing mass. Finally, a pre-stretched interior jersey retains its form for maximum flexibility and snaps back for ultimate warmth and comfort. Built to last.
Fluid Seam Weld – A revolutionary seam construction that utilizes a non-chafing high-grade silicone-based urethane applied in liquid form to the outside of a glued and blindstitched seam completely blocking out water without restricting flexibility.
Fully Taped Seams – The lightest, stretchiest neoprene seam tape ever. Applied 0.5mm split-neoprene to triple-glued seams with water-based glue to keep you dry and loose.
