This revolutionary material features clinically proven Smart Fiber Technology that converts body heat into usable infrared energy for greater warmth, increased endurance, faster recovery, and enhanced overall performance. The infrared print TDC is a low pile material for maximum flexibility, and is faster drying and lightweight, in and out of the water. Quick Dry Lining More lightweight inner lining with faster drying time; made from recycled polyester fibers. Ultrastretch Neoprene Comfortable, lightweight neoprene with softer foam and a tighter weave textile for less water absorption and better durability. Texture Skin Texture embossed rubber that provides excellent wind resistance; ideal for outer chest panels hoods, and other areas that would otherwise lose warmth quickly. Construction Inner waterproof stretch Fusion taping fuses seams together; used primarily in the upper body where maximum flexibility is required.  Pressure Bonded Seams A glued & blindstitched seam using pressure to bond panels together for a highly durable yet still flexible seam; finished with inner taping for comfort; used primarily in the lower body (taping color varies by product). Glued & Blindstitched Seams A fully sealed, maximum stretch seam construction that keeps water out. Neoprene panels are glued and pressed together, then blindstitched (needle doesn\'t fully penetrate neoprene, keeping water out).
