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 suit. 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 to hug the body for ultimate warmth and comfort. Built to last.

TechnoButter 3 Firewall – The most insulative, lightest neoprene foam core ever, with a heat retaining thermal interior layer and quick dry properties.

TechnoButter Fluid Seam Weld – A revolutionary seam construction that utilizes an 8mm 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.
