3mm Open Cell Wetsuit in all black with white ''Neritic'' logo is perfect for freediving and spearfishing. Made from 3MM thick, 39 Yamamoto limestone neoprene with durable super stretch lycra exterior. 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.
