When needed, go 800 lumens turbo with both LEDs for 30 seconds. Perfect for navigating dark situations, spotting signs or checking road conditions from a distance.

The headband is reflective for visibility, has a hollow band for breathability and silicon strip to divert sweat from your eyes.

A glow in the dark battery compartment aids in battery swapping on the go. Takes just under 2 hours to charge the included HLB1300 li-ion battery pack.
