The ultralight Silva Trail Runner headlamp allows you to exercise anywhere, at any time. The ergonomic headset with an extra wide, anti-slip band remains comfortably in place when running on bumpy ground. The two AA battery-pack is lightweight enough to fit on the headband; combined with the minimal lamp weight it's perfect for training. Trail Runner features Silva Intelligent Light® technology comprising both a strong light for distance, and the floodlight necessary for close-up vision.
