When it comes to UV pants, you want the comfort of your favorite sweats – without the weight or bulk. Our Windley Beach Pants fill the bill, offering full-length leg protection in our ultra-light, breathable ZnO™ fabric. ZnO™ fabric 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. Pair these sun pants with a beach cover up for the very best after-swim protection. They're perfect with our ZnO Seaside Hoodie or Sun Wrap.
