100% UltraStretch Neoprene – Comfortable, lightweight neoprene with softer foam and a tighter woven textile for less water absorption, better durability and maximum stretch.

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.

OS Back Entry – Smarter offset ("OS") back entry design keeps the zipper off the spine to reduce pressure and increase flexibility and comfort; with glued and blindstitched zipper flaps and a reinforced zipper base.

DuraFlex Knee Panels – Contoured, durable panels that stretch with you.

Water Barrier Inner Dam – Inner neoprene dam rests between zipper and your back, maximizing warmth and minimizing flushing.

Glued and 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). Can be finished with seam taping for added stretch, durability, and comfort.
