Protecting your core body temperature is important, especially in water where you lose body heat 20 to 25 times faster than in air. Aqua Sphere's Men's WT80 shorty is designed to do just that. Thermo-Guard Technology is used to provide maximum thermal insulation in a shorty that is ultra-light and durable. Strategically placed .5 and 1mm thick glide skin neoprene puts thermal protection where you need it without sacrificing ease of movement. Other features include a double-lock collar, special crotch panels to prevent chafing and an easy-pull back zipper for easy donning and doffing. This suit is perfect when engaging in 80 degree or warmer water activities.
