Very lightly worn (maybe 5 times?) women's Patagonia Tropic Comfort crewneck long sleeve; size Medium. I think this shirt was originally designed for fly fishing, but it's very versatile and is UPF 50. It has thumbholes, a back zipper pocket, and somehow a material that is both light and substantial. Selling as it no longer fits me, and comes from a non-smoking no pet home. *apologies for inconsistent lighting in the photos - the shirt is a pretty true lavender/gray color combo. Product Details from Patagonia: 94% polyester/6% spandex jersey with 50+ UPF sun protection and Polygiene® permanent odor control. Fair Trade Certified™ sewing Rear zippered security fly-box pocket Thumb-holes for added sun protection for the backs of the hands
