The Trail Runner Free Ultra is a light and streamlined headlamp that exists to illuminate your low-light runs. Two included battery packs give you a USB-powered option and a replaceable battery option. Equipped with Silva’s intelligent lighting optics, it offers a mix of flood and spot lighting, letting you see where you're headed and where you are.

  • Free Technology™ integrates the cord between the battery pack and the light into the headband, so there is nothing to snag or bounce around
  • 4 modes: high (400 lumens), medium (200 lumens), low (50 lumens) and flash
  • Intelligent lighting combines flood and spot lighting, covering the near and the far
  • Dual battery packs give you options: use the large USB-powered pack for long runs from home or anywhere you have easy access to USB, and enjoy the convenience of the AAA battery pack while traveling – the AAA is the world’s second most readily available battery
  • Included hybrid battery case has a rear facing red light that helps keep you seen
  • Battery extension cord gives you the option of putting the battery pack in your bag or inside a jacket pocket, which removes weight from your head and lets you keep the batteries warm for better cold-weather performance
