Proprietary “Blue Trilobite Camo” wetsuit, using 5MM thick, 39 Yamamoto limestone neoprene with durable super stretch nylon outer fabric. Smooth skin face, wrist and ankle seals to avoid water transfer, keeping your body temperature more consistent. All seams use a technique called “Blind Stitching” making the suit more comfortable and allowing for your chest to expand during peak inhalations. The chest pad is a 7mm thick neoprene, stitched and glued to ensure durability for repeated use.
