PETZL R1 Extension Cord

The R1 Extension Cord allows the user of the Nao RL headlamp to carry their battery somewhere other than their head. This helps lighten the load placed upon the head and neck, which over the course of a long race, isn't insignificant. If using the headlamp in the winter, the extension cord allows the battery to be stowed in a warmer place, thus improving battery life. No matter if you are skiing or running, the R1 Extension Cord is a smart choice. The cord is 110cm long and weighs ~50g.
