A gutter for your head?
I did not think this was real, but there are 143 comments on Amazon (many postitive):
And a video review claiming it is better than a Halo headband:
Who knew your head needed gutters.
I would rather just have a towel to wipe my face or head off than have the sweat directed so somewhere else on my body.
I like my halos, but I’ve been trying bikram yoga, and still get sweat in my eyes.
I wonder how well it works if my head’s going to be in any position other than “upright”.
"It blends the efficiency of a rain gutter within an ultra-comfortable sweatband system. The soft plastic gently adheres to your forehead without feeling tacky. "
My, but that sounds unappealing.
