Searching for sun shirts that will go with anything in your wardrobe? Our ZnO Long-sleeve T-Shirt is a solid choice--and a great value. Dress it up or down, wear it solo or layered: the choices are yours. Plus, the shirt features our most advanced fabric technology 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. Buy several colors and expand your mix-and-match options!
