5.11 Tactical - Flex-Tac TDU Rapid Long Sleeve Shirt
Engineered specifically for law enforcement and operators who require speed and mobility, the 5.11 Tactical Flex-Tac® TDU® Rapid Long Sleeve Shirt is a hybrid tactical combat shirt for plate carrier wear and dynamic field operations. The upper body is constructed from 6.2 oz Flex-Tac® poly/cotton ripstop with mechanical stretch - rugged enough to take the brunt of vehicle work, breach entry, and rope work where the shirt takes the hits. The lower body switches to a lightweight 3.7 oz polyester/elastane plain weave, designed to manage heat and stay low-profile under a plate carrier or chest rig.
Strategic mesh panels in 5.0 oz cotton/polyester/elastane mesh sit on the sides and at the underarms, delivering targeted ventilation where heat builds up fastest. Reinforced articulated elbows add prone-position durability and freedom of movement, while flat-lock seams throughout prevent the chafing that destroys comfort under hours of armour wear. A Teflon™ finish on the upper body repels water, dirt, and soil, keeping the shirt sharp through messy operational conditions. The 1/4 zip front allows for rapid ventilation when conditions heat up and easy donning or doffing over base layers. Low-profile shoulder pockets with hook-and-loop closures handle quick-access storage, while integrated loop platforms accept unit ID, rank, or morale patches. A dedicated pen pocket on the lower sleeve rounds out the operational layout.
