They say good things come in threes and the Armachillo® Cooling Underwear 3-Pack proves the rule! Microscopic bits of jade embedded in the fabric feel cool to the touch, while the nylon/spandex knit wicks sweat and moisture from skin – keeping you comfy all day. Flatlock stitching keeps a low profile and the chafe-free, no-shift fit keeps ’em in place as you work and play.
