I know I've mentioned this in another thread or two but the halo headbands don't work any better/longer than a cheap cotton headband for me, dripping into my eyes after about 30 minutes. I have 4 different halo models (skullcap, wide, regular, narrow). Lately I have been using a SweatBlocker Headband from Original Free Range (
