Product details:

Specifically made to be worn under an external vest carrier, the 5.11 Long Sleeve PDU Rapid Shirt uses dual fabric construction to keep you comfortable. The upper body is made from a toughened polyester/cotton blend, while the lower portion is made from an agile cotton/polyester/spandex performance knit. This shirt is built with antimicrobial and moisture-wicking materials to not only dry quickly, but to prevent the growth and spread of odor-causing bacteria. A DuPont Teflon treatment on the upper body resist stains and moisture. The shoulders are reinforced to support the weight of a vest without breaking down.
