Quick Overview


Silva Trail Runner 4 Ultra (including Li-Ion and battery pack)

Silva's torches are a level above their competition with longer burn times, exceptional built quality and robust simplicity.  Perfect for longer runs on winter nights the Ultra comes with a rechargeable Li-ion USB battery, AAA battery pack and an extention cable to keep the weight off your head. It also keeps the battery warm meaning it'll run for longer when the mercury plumets, this feature benifits not only runners but mounatineers that'll need relaible hours of light. For example with AAA's at -5 you'll get about 10 hours at full blast (350 lumens-75m~) and if you can keep the battery warm inside your jacket you'll get more like 25 hours; the difference is surprising.

Silva's description:

Got any long races coming up? Or are you the kind of person who just wants to keep running? This headlamp will not let you down. It comes with double battery packs to give you as much burn time as possible and is built to withstand all types of weather.

With its double battery packs, Trail Runner 4 Ultra offers you a very generous burn time of 90 + 18 hours – which you can extend even further, by simply bringing some extra AAA batteries. It comes with a comfortable anti-slip headband, a SILVA Tyto safety light that makes you visible in the dark and an extension cord, which lets you carry the battery packs in your pocket. So regardless if your next race is for charity, a gold medal or simply because you love it, Trail Runner 4 Ultra will be a perfect companion you can trust, all the way to the finish line.
