Painful nipple abrasion is a common problem experienced by male athletes that is typically caused by a sweaty shirt rubbing up against the tip of the nipple over extended periods of time.  The problem also occurs when weather conditions are less than perfect, such as with high humidity, rain and snow.

NipGuards® patented design uses a medical adhesive that sticks on the base of the nipple, with a hollow cavity covered by a protective layer that shields the tip of the nipple from rubbing against the shirt.  Because you do not sweat through the base of your nipple, NipGuards® will not fall off due to sweat.  When applied properly, NipGuards® will stay on in all weather conditions for any distance, including 100-mile ultra marathons and full triathlons.
