Black Diamond Cosmo 350 Headlamp
Description
With 350 lumens of power housed in a super compact, watertight body, the redesigned Cosmo is perfect for urban adventures and overnighters in the woods. The Cosmo is constructed partially from recycled materials, and the user interface includes a second switch for easy lighting mode selection. Its Dual-Fuel versatility means this headlamp runs on either a rechargeable BD 1500 Li-ion battery (sold separately) or with three AAA batteries.
