Zone3 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 and heat bonded to reduce water entry. Durable and comfortable, high visibility details make you easier to spot in the water.
