Featuring a sleek design and ample feature set, the 90-lumen Cosmo headlamp is at home cooking dinner at the campsite or rappelling off a multi-pitch route after the sun goes down.

Standard distance and proximity modes, both dimmable, are complemented by a red night-vision mode — extra handy when waking in the middle of the night — and all modes are accessible via one simple-to-use button. With a housing built to withstand sprayed water from any angle, the Cosmo is ready to handle any storm on your epic adventure.
