In the past, other brands have tried to help that process by developing fabrics that wick moisture away from the skin and expedite evaporation. For over 10 years now, De Soto has taken this concept a step further by using that moisture to create a cooling effect. YES! WE WANT YOU WET. Skin Cooler works by a series of channels knitted into light fabric. As these channels get wet, they absorb moisture and swell, which dissipates the heat making the fabric against your skin actually cooler. How much cooler depends on factors including airflow, humidity, ambient temperature, and moisture temperature. When you sweat, the garments temperature drops and creates an actual cooling sensation. Skin Cooler SDS offers this cooling effect while offering even more sun protection.
