You are much better off with a purpose built headlamp that gives the ability to tilt the light. The headband style flashlight holders just dont work that well imo. I would pick up one of the great H600/602 series headlamps to match your Zebralight and then you will have an amazing combo with the same UI and battery:thumbsup:
If you are hell bent on a headband though I believe Fenix, Nitecore, and Nite Ize makes them. There may be others as well.
IMHO , it would be better to get headband model like H600 series. I own both Fenix headband and H600FW.
I feel that H600FW is much more comfortable to wear than the Fenix.
