Abstract: The “NO SWEAT” device is an absorbent device designed for use with a head cover to prevent the flow of perspiration onto the face of the user and primarily intended to keep perspiration out of the eyes of the wearer. It was conceived as a product for people engaged in outdoor activities in hot weather conditions such as sports activities. It may also be useful to people who work under hot lighting conditions or stressful conditions as may be found in hospital operating rooms or by troops operating in high temperature areas when the removal of their helmets may constitute a danger of exposure under fire. The device also provides protection from sweat stains to the head covering. This device contains an absorbent material which can absorb as much as 200 times it's volume and lock it into the surrounding material. We know of no other product currently on the market to do what this device is designed to do.
