With 300 lumens of power housed in a super compact, watertight body, 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. 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.
