Keep cool and comfortable while at the office or on the water with the AFTCO Sirius Tech Button-Up Long-Sleeve Shirt for Men. Lightweight, yarn-dyed 100% polyester construction along with vertical rear ventilation keeps you cool, while AFBLOCK UPF 50 sun protection keeps harmful rays from damaging your skin. AFGUARD stain-release performance keeps fish gunk from setting into the fabric, meaning it washed out easily at the end of a profitable day on the water. Dual front chest pockets with snap closures offer a classic, clean-cut look, while bi-swing construction and articulated shoulders ensure maximum, unrestricted motion for optimal comfort. What’s more, this shirt features a small microfiber lens cleaner cloth on the inside to keep your glasses clean, without carrying a glasses case around all day.
