Rugged and weather-ready

The Cosmo 350-R is IP67-rated, meaning it can handle rain, splashes, and brief immersion. Its lightweight, low-profile design rests comfortably on the head, while an adjustable strap keeps the fit secure during long nights of hiking, camping, or early-morning setups.

• IP67 waterproof housing for rain and immersion up to 1 meter for 30 minutes.
• Balanced beam to support both close-up tasks and longer-range visibility.

Real-world appeal

In everyday outdoor use, this headlamp shines when you’re pitching a tent, tying knots, reading a map, or getting meals ready after dusk. The red night-vision option helps you preserve night vision and keep conversation undisturbed at the campsite.

Why it stands out

With a compact footprint and dependable performance, the Cosmo 350-R blends simplicity with capability. It’s a thoughtful choice for campers, hikers, and weekend explorers who want clear visibility without bulk or complexity.
