Divers seeking a great value will appreciate Thermoprene's balance of performance and price. The material combination delivers greater flexibility and improved features not found in standard neoprene wetsuits, yet at a reasonable cost, perfect for the cost-conscious buyer. Thermoprene is crafted from a high-quality neoprene and a low pill fabric. It has 75% more stretch than standard neoprene, so while it is not as flexible as Henderson's Thermoprene Pro or TherMAXX lines of products, it still boasts significant comfort characteristics. The 180° stretch Thermoprene is noticeably easy to don, pulling over the feet with less huff and puff than standard boots. Also, the fabric's exterior stands up extremely well to the wear of fin straps and foot pockets with its pill/abrasion-resistant exterior laminate. The Thermoprene boot line from Henderson Aquatics delivers quality and performance a step above the rest. A fantastic value. Get the features and design benefits of more expensive boots in this economically priced boot ideal for both local waters and exotic destinations.

These 3mm nylon 2 neoprene boots come equipped with a #10 heavy-duty zipper closure and Water Entry Barrier (WEB) for added comfort and warmth.
