Why We Like The Psycho Tech 4/3+mm Back-Zip Full Wetsuit

O'Neill's Psycho Tech line puts emphasis on heat-retention with an extra half-millimeter of thickness and warmth-generating neoprene in key areas so we can shred off-season surf. O'Neill is regarded for its flexibility, and this cold-water suit is no exception. TechnoButter 3 is both stretchy and thermal, and the wetsuit's stitchless seams increase flex even further.
