Featuring a redesigned waterproof housing and 200 lumens of power, the Black Diamond Cosmo Headlamp is perfect for any adventure where daylight is in short supply. From dinner in camp to alpine starts and late-night hikes, the Cosmo features six different lighting modes for fully custom illumination. And thanks to its fully waterproof construction, the Cosmo keeps lighting the way through sprinkles, splashes and full-on storms.
