These days, it's business as unusual – yet you handle all the snafus and surprises without breaking a sweat. Your secret? Cool-inducing Armachillo® Undershirts. (We’re told that, for many men who work from home, it’s ALL they wear!) And no wonder. The silky, stretchy 4.9-oz. 91% nylon/9% spandex knit fabric is infused with microscopic jade that disperses heat – giving it cool-to-the-touch comfort unlike any other undershirt. Plus, it wicks moisture – never feels clammy or clingy like cotton can. And resists odor and mildew, keeps you smelling fresh if showering doesn’t make it to the top of your must-do list. Ultra-smooth side seams stop chafing cold, and a sturdier rib neck never slouches out of shape. Stay chill, men!
