Nipguards

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.
