Truthfully it would be quite foolish to miss out on this 4/3mm Men's Quiksilver SYNCRO PLUS B/Z Fullsuit. Why? Because it is chock-full of the latest and greatest wetsuit technology. Not only is it made with 100% stretch StretchFlight limestone-derived neoprene for a seriosuly stretchy, soft, lightweight, and warm fullsuit, it's also got a WarmFlight x1 Far-Infrared thermal lining on the chest and back panels which transforms your body heat into infrared energy for warmth and a quick-drying experience. Other awesome features include: Vapor stretch on the back panel which captures the sun and retains heat, durable and zero leakage sealed and Liquid Flex Seal externally taped seams, a full back zip entry, drainage holes, Hydrowrap x2 adjustable neck closure, a Hydroshield water barrier to prevent water from entering, and strong/lightweight Ecto-Flex knee pads.
