U.S. Cavalry's TRU Combat Shirt reduces the severity of burn injuries, integrates well with body armor and is lighter and more comfortable to wear in hot and humid environments -- a base layer and tactical uniform. The Combat Shirt concept improves the design of the tactical uniform by: reclaiming cargo pockets and placing them on the sleeves in a more practical arrangement; reducing weight by eliminating excess uniform material and need for separate base layer; and creating a comfortable, durable and naturally thermal resistant body that also wicks moisture. The full function sleeves are based on the TRU uniform and available in two high performance fabric options. Both are tough, durable and field tested to ensure dependable service under the most challenging conditions. Sweating the details, TRU-SPEC also added underarm gussets for increased motion and a padded, abrasion-resistant elbow patch for durability. The sleeve layout is improved with a zippered storage pocket and pads for insignia as well as hook and loop cuff closures. Special care was taken to reduce chaffing and other irritations; the mock turtleneck keeps body armor from rubbing against the neck area while seams fall off the shoulders to reduce pinching. The body of the TRU Combat Shirt is made from Cordura brand Baselayer. This 60/40 cotton/nylon miracle blend insulates the body when exposed to high temperatures and will not drip or melt onto the skin like polyester. Cordura Baselayer fabric is also breathable, wicking away moisture 2.5 times faster than 100 percent cotton, plus it dries quickly. Even though the fabric is soft, lightweight and comfortable, Cordura adds tough-as-nails durability needed to minimize tears and other abrasions. The TRU Combat Shirt is available in ACU Digital and MULTICAM with 50/50 cotton/nylon rip-stop blend sleeves. Black, Khaki and Olive Drab are available with 65/35 poly/cotton rip-stop sleeves. All colors are available in small through 2XL.
