Silva - Trail Runner Free Extension
Silva Trail Runner Free Extension
Running or paddling at night with a heavy battery pack on your forehead is a balance and comfort issue that adds up fast over a long outing. Moving that weight to your pocket is a simple fix, and that's exactly what the Silva Trail Runner Free Extension Cable makes possible.
The 85 cm cable connects your Trail Runner headlamp to a battery pack carried in a vest pocket or pack hipbelt, shifting the load off your head and improving comfort and stability during high-movement activities. The woven exterior has a soft, flexible feel that resists tangling and holds up to repeated use without stiffening or cracking in cold temperatures.
It's rated IPX5, so it handles driving rain and spray from any direction without issue, which matters whether you're running a wet trail or paddling in choppy conditions. The cable is also compatible with the Silva Hybrid Battery Case (sold separately), giving you the option to run higher-capacity power on longer efforts. Lightweight and compact enough to tuck into any kit bag.
