Duo RL Headlamp

Why We Like The Duo RL Headlamp

Our 100-mile race has us running through the night with little sleep and questionable cognizance, so we rely on Petzl's Duo RL Headlamp to illuminate uneven terrain, low-hanging branches, and "wrong-way" course markings. When our energy level allows only for placing one foot in front of the other and maybe moving food to mouth, the smart lighting adjusts to the surroundings for us.


  • Brightest headlamp Petzl has ever made for ultimate visibility
  • Reactive Lighting tech automatically adjusts brightness and pattern
  • Customizable standard lighting levels (5) for your specific needs
  • Rotating selector knob for easy operation while on the move
  • High-capacity rechargeable battery sits in rear for ergonomic bliss
  • Dustproof and waterproof to withstand extreme weather conditions
  • Aluminum lamp body protects bulbs against falls and compression
  • Conveniently compatible with all existing Duo accessories
  • Item #PTZZ242
