Since when is a button-down so flexible and tough? Since now. The Alpha Flex Long Sleeve Shirt would look great in a boardroom, but that would be a waste of advanced garment technology. From the stretch collar to the poly/cotton dobby stretch fabric, this shirt bends and flexes right along with you, whether you're tracking a suspect or working a long shift on event security. It's even got impact-resistant buttons if things get a little intense. Add an Alpha Flex or two into your Mission Ready™ covert wardrobe and be dressed for some serious action.
