Needing a light after dark and not having one is a major bummer. The Cosmo Headlamp ensures that you'll never be without light in times of darkness thanks to its ultra slim design and incredibly low weight. The Cosmo doesn't skimp on brightness either, cranking out 90 lumens via spotlight and proximity modes. The dimming features allows battery conservation when you don't need full power lighting and the red light mode let's you stargaze without going completely dark. Have you ever crammed your headlamp into your pack only to arrive at your destination and realize you are now almost out of batteries? The Cosmo combats incidental button jostling with an ingenious lock mode, that keeps the light off when you don't need it, ensuring full strength illuminance when you do. All of this functionality is controlled with one button, making on the fly adjustments extremely easy. Additionally, the Cosmo is water resistant, making the afternoon thunderstorm a mere inconvenience instead of a lightless epic. Small, rugged and indispensable, the Cosmo Headlamp is ready to illuminate your adventures both big and small.
