The Fenix AFH-03 Replacement Headlamp Headband has perforated material that reduces weight and creates a more comfortable feel. The built-in sweat ring helps channel moisture away from your eyes.
Very comfortable and secure…much better than the original over-the-head strap which lost its elasticity and was difficult to adjust.
Cant replace the headband
What light are you trying to replace the headband on?
I have an old HL21 headlamp and the rubber in those old Fenix head bands seemed to wear out really fast, so it was basically useless. Picked up one of these, and while essentially the same layout and system as the old ones, the materials are much better. They dry faster, and the strip in the front keeps it from sliding into your eyes. I must have a fat head though, as it's almost all the way down on adjustment, but still fits comfortable with long hair.
