Zone 3 developed the Aspect Thermal Wetsuit for open water swims in the colder months. With an Aqua-X coated Smoothskin material on all panels except the crotch, this wetsuit is best suited to breaststroke or front crawl. Made from 2-5mm thickness neoprene, it gives warmth while allowing a balanced body position in the water. Inner Heat Tech thermal lining panels keep key muscle groups better insulated. All the main body panels are glued & heat bonded to reduce water entry. Durable & comfortable, high visibility details make you easier to spot in the water.
