When a heat dome targets Texas, average temperatures can easily blast past 100°F. In a simmering situation like that, a man needs all the cooling power he can get. So ditch the hot, sticky cotton undies and pull on the revolutionary cooling of Armachillo® technology. Microscopic jade embedded in the fabric feels cool to the touch and actually lowers body temperature. The smooth, stretchy knit fabric wicks sweat from your hide to stop chafing, and a special fabric treatment even stomps out odors. Grab a couple of pairs and keep your cool no matter how much summer simmers.
