The Sparco Micropoly karting underwear is made from Coolmax material, the most advanced and innovative Dupont fiber (not fireproof). The underwear is also treated with X Cool Silver that draws heat from the body surface to cool the driver. To maximize sweat absorption and to guarantee comfort, even in the hottest conditions, this underwear must be worn tight on the body.
