Product Details
The Black Diamond Cosmo 300 Headlamp is perfect for urban adventures and overnighters in the woods. The Cosmo's new, compact body is more ergonomic with a lower profile for improved balance, and the updated user interface includes a second switch for easy lens selection. In addition, the updated optical efficiency not only provides brighter light, but also saves battery life. And thanks to its watertight construction, the Cosmo keeps lighting the way whether you're forced to bike home in the rain, or you're hiking back to camp in an unexpected downpour. It is waterproof-Tested to operate at least 1.1 meters underwater for 30 minutes. If submerged, water may enter the battery compartment and it will still operate; it should be completely dried out after use in wet conditions.
