Usually you have to choose between comfort and usability. Meet the Intersection of the two in AFTCO's Intersection button down shirt. Made with 100% polyester yarn dye, this short sleeve shirt will be the comfortable shirt in your closet. AFBLOCK UPF 50 sun protection and AFCOOL moisture wicking make this shirt as useful as any other AFTCO performance shirt though. Add in an integrated microfiber lens cleaner for you phone and glasses, and you have the most comfortable and useful shirt you will own.
