Inspired by the iconic military fatigue pants. The OG-107’s first saw production in 1952. The original version of the army green pants are called OG-107 Utility Pants. “OG” stands for Olive Green and “107” is the color code of US ARMY for green. They were made for US Army soldiers for training and utility work purposes. Our Nam Fatigue Pants came in different shade and material of the original. Made from 100% cotton twill in neutral khaki color shade. It’s really a timeless and versatile piece to wear nowadays.
