The Sun Stretch Shirt is our Womens&'; staff favorite for tropical conditions. Super lightweight and breathable for long days in the sun. TCO script logo on the sleeve for added coolness. Description Built for warm weather fishing, Patagonia&';s ultralight, fast-drying Long-Sleeved Sun Stretch Shirt is made from a stretchy 2.3-oz 52% nylon/48% polyester blend that offers plenty of freedom to move and breathe. Providing 30-UPF sun protection and full-arm coverage through the heat of the day, its comfortable, relaxed fit works beautifully when worn over a bathing suit or under a warmer layer when evening temperatures drop. Snap-down collar points prevent chin chafe. Two button-closure patch pockets on the chest; a hidden zippered security pocket on the left chest holds small essentials. A convenient front interior sunglass wipe panel keeps your field of vision clear. Curved hem falls to the hips.
