Add a dash of panache to your sunwear collection. Our elongated ZnO Boyfriend Cardigan has gold buttons for a slightly dressy look and a supremely soft touch like your favorite comfy T-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.
