Built for comfort and performance on the water, the Simms Women’s Bicomp Long-Sleeve Shirt is made with COR3 technology that wicks moisture, dries quickly, and provides you with UPF 30 sun-protection through long days on the river. The COR3 tech is made from a breathable polyester fabric to handle hotter days spent on the trail or by the water, and is finished with an anti-odor treatment to keep fishy smells at bay. Knit sides and sleeve panels further add to your comfort when you’re tossing flies, and the sunglass chamois on the inside bottom hem keeps your shades clean after catching some errant spray from splashing fish.
