Our premium Japanese sourced chambray is a 7.5oz plain-weave fabric that closely resembles denim but is made from cotton with a colored warp and a white weft. This gives it the distinctive light blue color that's often associated with traditional American work shirts. The fabric became a staple in American workwear in the early 20th century. It was valued for its durability, comfort, and breathability, making it an ideal choice for workers in various industries, including agriculture and manufacturing. During World War II, chambray shirts were standard issue in the U.S. Navy, were often worn under denim dungarees creating a durable and functional uniform that could withstand the rigors of daily labor.
