Here is a magnetic nasal band that helps athletes maximize their performance. The Intake bands are designed to open your nasal passageways to their widest capacity, so you can achieve a deeper breath every time. Using these is pretty easy too. Simply clean each side of your nose, use the applicator to apply adhesive tabs to each nostril, apply the band over your nose, and wait for the magnetic ends of the band to click into the tabs.
This neat breathing system is getting funded on Kickstarter. It is expected to ship in September.
