    Comments about Black Diamond Cosmo Headlamp:

    We just used this headlamp on a bike camping trip and couldn't be more stoked! The headlamp is light and durable, taking three AAA batteries (included) to light it up. The dimming feature on the lamp is awesome and was greatly appreciated by those hanging out around us. It's easy to setup, easy to adjust and a must-pack on any outdoor adventure!
