Trail Runner Free 2 Extension Cable is a great companion to your Trail Runner headlamp. Having an extension cable enables you to keep the battery in your pocket instead of your headband. Fits the Trail Runner series along with the Hybrid battery case (purchased separately).
The extension cable meets the IPX5 standard which means that it can withstand heavy rain and water from any direction. Length of the cable is 85 cm and it has a woven cover that feels soft like a shoelace.
