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.
