The Black Diamond Storm 450 headlamp is sealed to an IP67 rating, built to keep out dust and grit as well as sustained water exposure, not just the occasional splash. Multi-colored night vision in red, green, and blue preserves natural sight in low light while peripheral lighting handles close-range tasks like rigging gear in the dark. Dual-Fuel compatibility and PowerTap Technology round out a headlamp built to run through multi-day trips without losing brightness or reliability. What Our Gearhead(R) Experts Are Saying:"Dust coated everything on a canyon approach that turned into a downpour by the time we set camp, and the Storm 450 never missed a beat through either extreme. That's the kind of sealed housing I stop noticing until the conditions actually test it."
