The A/C Shirt stands for two things: always cool and always comfortable. Lightweight button up shirt with airy short sleeves. Ironing is optional thanks to the intentional wrinkly woven fabric. Open patch chest pocket. Straight hem with side slits that increase mobility. 100% organic cotton. Machine wash warm, tumble dry low. Product measurements were taken using size S (7/8 Big Kids). Please note that measurements may vary by size.
