This versatile ultra-thin neoprene steamer can be used for thermal protection while pool training, as a warm-water wetsuit, or as a base layer beneath a thicker wetsuit for cold-water diving. Made from extremely soft 0.5mm neoprene with a stretchy Nylon 2 Sides lining, this lightweight steamer comes with 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 increase durability while maintaining comfortable flexibility in the leg areas.
