The US Airforce OG 507 Fatigue Shirt is a staple in military workwear. This shirt is made from a comfortable and breathable US Military OG 507 poly cotton fabric. Some shirts features several patches, such as one with the original wearer's name, a patch for the 67th Civil Engineering Squadron, and a Tactical Air Command patch. Not every shirt features the same patches as those show in photography, making each piece unique. As a rugged and unique piece, this Airforce shirt is a must-have for any collector.
