EC2 Qwik-Dri fabrics offer body-activated comfort: they respond to your body's needs, whatever you happen to be doing, by pulling moisture off your skin, creating cooling evaporation. The evaporation takes place rapidly, three times faster than typical wicking fabrics perform, keeping you dry, warm and comfortable, ready to once again insulate you as soon as you stop exercising and your body's heat and moisture production drop. Since the EC2 Qwik-Dri process alters the molecular signature of the yarn in our fabric, the moisture control is permanent. It won't wash out or wear off.
Ultraviolet Protection Factor (UPF) is a measure of the percentage of ultraviolet sunlight that reaches your skin through a given fabric, estimating the additional amount of time you can spend in the sun with a certain garment on. (UPF 25 meaning you can withstand 25 times the amount of sun you could without protection).
