Puff, puff, give: The Volcom Modulator 4/3mm chest zip wetsuit takes all the warmth of its hooded brethren, but blows off the hood. Made of high quality neoprene — limestone-based Eco Carbon Black, which is better for Mother Earth — the Modulator 4/3 stays toasty. A fuzzy fast-drying thermal lining in the chest, back, and upper legs adds mind-blowing warmth. Blind-stitched, glued and fully taped seams, plus wrist and ankle seals and a YKK chest zip, keep cold water out of the party. A surf-specific fit and the neoprene’s 4-way stretch pattern make next-dimensional surfing a reality for those willing to pursue it, even on cold-ish days.
