Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


With just a high and a low mode, there's nothing to get in the way of your "go mode." The Trail Runner 4 Ultra is a simplified, but not basic, 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.

  • Intelligent lighting combines flood and spot lighting, covering the near and the far
  • Dual battery packs give you options: use the USB-powered pack for short trips 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
  • 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
  • LED power indicator lets you know when your batteries need swapping or charging
  • Anti-slip headband stays in place when on the move
  • Large, 1-button interface is easy to use with and without gloves
  • Includes the Twin Tyto red rear safety light, great for when events or activities call for a safety light. Twin Tyto uses 2 CR20302 batteries for 24–100 hours of runtime, and is certified to IPX6 weatherproofing
  • Lumens and runtimes measured to the ANSI/NEMA FL1 standard
  • Overall IPX5 waterproofing stands up to any weather you’re willing to go out in
  • In the box: Trail Runner 4 Ultra headlamp, 3 x AAA battery holder, 3 x AAA batteries, rechargeable 2.4Ah battery pack, extension cable and Twin Tyto red rear safety light
