Heading to the gallery at the golf club? An outdoor wedding? You never know when you might need a little shade for your arms and shoulders. Our versatile Marietas Sun Wrap offers the same reliable UV coverage as our sun shirts, in a go-anywhere package. The wrap features a technology called ZnO fabric. ZnO 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 a wonderful way to cover up quick-and give casual looks a little extra flair.
