WOOLRICH ELITE SERIES MEN'S LONG-SLEEVE SHIRT - The Elite Long Sleeve Shirt is loaded with features that make practical sense. It’s designed to adapt to the weather and keep you comfortable no matter how active you are. Constructed of cool, 100% cotton poplin fabric for extra comfort and reactive dyed to ensure a superior level of fade resistance. To further enhance durability, the fabric is treated with DuPont Teflon stain protector. This offers a breathable, durable barrier that repels both water and oil based spills. The shirt is garment-washed for a soft, broken-in feel. To protect you from the damaging effects of the sun’s ultraviolet rays, the fabric is treated with UV protection. Even wet, you have an Ultraviolet Protection Factor of 30 (UPF is similar to the SPF rating used in sunscreens)
