Headlamp Silva Trail Runner Free Ultra

SKU: 37807

On this fifth generation of our original running headlamp, we present a new kind of technology where the power cord is integrated into the headband. We call it Free Technology – a comfortable headlamp experience without distracting cords or tangled wires. No hassle – Just free the energy.

Hybrid Battery Case Included
The Hybrid battery case can carry either the rechargeable Silva Hybrid battery pack or 3 x AAA batteries (not included). This means that you have can use AAA batteries as a backup if you run out of power. The case has grip friendly surfaces and holds an integrated red rear safety light – adding extra visibility.

Long Distance Battery Included
In addition to the Hybrid battery case that gives you multiple battery options – Trail Runner Free Ultra comes with a rechargeable, long lasting 4.0 Ah battery pack that sits neatly in a multi attachment soft case. The 4.0 Ah battery is perfect for extended burn time on those longer running sessions. The battery has 4-step battery indication and can be charged anywhere, using the included USB cable.

Customized Light Distribution
The Trail Runner Free series is made for running in every aspect. All three headlamps feature Silva Intelligent Light. This means that you get a double light beam technology in your headlamp, with light settings that are perfect for running. Our unique combination of a long reach spotlight and a close flood-light, results in less head movement, better control, improved balance, less fatigue and higher speed.

Comfort In Every Detail
Despite the focus on technological breakthroughs, we have not forgotten about the importance of weight optimization. Every part of the headlamp has been compressed and the unit only weighs 55 gram (excl. Batteries). Even when using the 4.0 Ah long distance battery, included with Trail Runner Free Ultra, the entire headlamp still only weighs 141 grams. The headlamp is perfectly balanced, with smooth adjustments and a flat, soft textile extension cord that doesn’t tangle. The headband is soft, yet firm enough, with a silicone string on the inside to stay in place. The battery can be carried comfortably on the headband or be kept warm in your pocket to save battery life by using the included extension cord.

Go Far Or Go Fast
Choose Trail Runner Free Ultra if you want to go for really long sessions with the 4.0Ah long-distance battery. With Free Ultra you also get the Hybrid battery case which can be used with either 3 x AAA batteries or by complementing it with a Hybrid battery (1.25Ah).
