The Asterisk AC System™is a two part magnetic nasal dilation device for use in off-road motorcycling, snow-sports, and MTB goggles. The purpose of this device is to enhance your nasal breathing ability. Studies show that nose breathing is the only way to properly condition the air you breathe for optimum performance. The AC SYSTEM™ functions magnetically. The steel nasal attachments and magnetic goggle clips allow room to flare the nostrils, enhancing your ability to nose breathe beyond normal capacity.
