5.11 designed its Taclite TDU SS Shirts to act as an upgrade to the aging BDU product lines. Made from a Taclite polyester / cotton ripstop fabric, these shirts offer lightweight, breathable comfort while remaining incredibly durable. The fabric is treated with DuPont Teflon to resist soil and stains, while bar-tacks reinforce high stress areas for long-lasting wear. 5.11's signature Hidden Document Pockets on the chest provide covert storage space for maps, IDs and other documents, while the bi-swing shoulders allow for a full range of motion. With durable melamine buttons and triple-stitch construction, this shirt is built to hold up in challenging tactical operations without giving up an ounce of comfort.
