One of the most often over-looked aspect with regard to in-water activities is heat loss. Heat loss in water occurs 20 to 25 times faster than in air. Aqua Sphere addresses this aspect with their Aqua Skin swim line which is temperature specific. The WT50 Women's Full Jumpsuit is designed for use in water temperatures of 50 to 70 degrees Fahrenheit (10 to 15 degrees Celsius). Using Thermo Guard Technology, .5mm and1mm Glide Skin neoprene provides thermal insulation designed to slow heat loss in water. For the active water enthusiast, this means a longer and more productive time. This suit is great for swimming, snorkeling and even triathlon training.
