The loose fit DRYSHIRT™ utilizes material that takes advantage of revolutionary technology. This is not a standard "Moisture management" shirt that simply wicks away sweat. Our material is much more sophisticated and takes advantage of a proprietary fluorocarbon technology that allows the material to literally assist in your own body's thermoregulation process! Through nanotechnology, our clothing remains water repellent from the outside while allowing sweat to breath through the fabric from the inside out giving you the most comfortable environment available.If you are looking for sun protection then there is no product available offering such a light weight and comfortable shirt yet maintaining a full 50+UPF rating (Equivalent to 150+ SPF). From outdoor activities that involve water to simply getting some quality time in the sun at the beach or even in the garden nothing compares to the DRYSHIRT™There is nothing on the market today that is anything like the with our exclusive Arid Core Technology™ (ACT)
