Hot-blooded sleepers know the struggle is real – waking up night after night sweltering, bathed in sweat and tangled in soggy sheets. Now you can chill out thanks to the same cool-to-the-touch technology that’s earned our Armachillo® Underwear thousands of 5-star ratings. Microscopic jade embedded in this Sleep Shirt actually lowers skin temperature, while the 92% polyester/8% spandex knit fabric wicks away moisture and fights odor. Lightweight and stretchy, this shirt never binds or chafes while you’re sawing logs. It’s the stuff dreams are made of!
