5.11's TDU Shirts are designed to exceed all MILSPEC requirements. Each features a covered placket, 5.11's patented hidden-document pockets, Velcro-closure chest pockets, and rear bi-swing shoulders. Elbows are double-reinforced and come with removable neoprene elbow pads. Like the pants, TDU shirts are triple-needle stitched and treated with Teflon. The shirt is available in long-sleeve, short-sleeve, and tall versions in either 6.14-ounce ripstop or 5.78-ounce twill. Also available in the TDU line is the 5.78-ounce poly-cotton twill TDU Jumpsuit. The design incorporates features like 5.11's hidden document pockets, BBS-compatible cargo pockets, removable knee and elbow pads, triple-stitching, and generous bartacking.
