MB, I saw it in sherrill a couple months ago. Then I saw them at the store just the day before yesterday. I have 1 concern, though. The concept makes sense- absorb the sweat and divert it away from your eyes.
for those of you that don't know, imagine a head-band sortof like what you see tennis players wearing, but on the inside, but a strip of thin rubber less than 1mm thick on the inside, about 1/4 inch from the bottom.
So I have this OTHER headband that is thinner than the HALO, but I wear that to cover my ear when it is cold or windy out. It fits under a helmet, so works well for tree work.
Here's my prob w/ HALO. I stay a LOT warmer when wearing my ear warmer head band. Halo is made of even THICKER material. I think though the halo will keep sweat out of my eyes, overall it will just make me warmer. Fixing one prob, but making another bigger prob.
I opted to keep my $14 and haven't tried it yet.
love
nick
