Who said UV shirts have to be plain, Jane? Our Lilac ZnO T-shirt showcases one of nature's most fleeting blooms, keeping you covered and cool in the process. Plus, the shirt features our latest technology development called ZnO SUNTECT®. ZnO SUNTECT® embeds millions of tiny particles of zinc oxide -- the same ingredient that is used to block UVA & UVB in better sunscreens and to treat mild skin irritations and burns -- into every fiber. These ZnO particles cannot wash or wear out. It's just the thing if you want a sun shirt with a pop of personality!
