This versatile ultra-thin neoprene steamer is perfect for thermal protection during pool training, as a warm-water wetsuit, or as a base layer under a thicker wetsuit for cold-water diving. Made from soft 0.5mm neoprene with a stretchy Nylon 2 Sides lining, this lightweight steamer features a vertical YKK zipper with brass slider for easy donning and doffing, and foot straps to prevent ride-up when used as a base layer. Printed kneepads enhance durability and flexibility in the leg areas.
