Sweat GUTR Sweatband - SMOKE

As this channels the sweat to where your ears are, does the sweat get into your ears? I wear earbuds while working all day.

Is there any polyester in the elastic band?

Will the sweat gutr work when i’m in my aero position on my tt bike??

do you make a bracelet version? would be good for sports where sweaty hands are bad like cycling, tennis, basketball, etc
