To help maintain a healthy body temperature at work, this synthetic space-age towel creates a cooling aid significantly colder than ambient air. Wear for hours to reduce the effects of heat stress and fight fatigue or wipe off for quick use. Simply dampen to activate fast and easy. Run under cold water for one minute for the advanced PVA cooling technology of the Chill-Its Cooling Towel to take effect. This technology holds water without feeling heavy. Simply re-wet the super-evaporative towel to reactivate. Towel is machine-washable so you can use it again and again.
