The Patagonia Men's A/C® Shirt is a finely woven short-sleeved shirt made of lightweight organic cotton. The design and fabric favour tropical climates; the performance keeps you sane in the August heat of Midtown Manhattan. Like air-conditioning for your skin, the A/C® Shirt has a breezy 100% organic cotton that allows maximum airflow. Its light fabric rests casually on your skin, and the clean design features only the necessities: button-through chest pocket and side vents at the straight hem. A reinforced collar maintains its integrity. Recyclable through the Common Threads Recycling Program.
