This is the best type of headband if you are doing high intensity activities as it never gets saturated. It will always keep sweat out of your eyes, except if you are leaning forward like for cycling in the drops. To fix this though you just look left or right every couple minutes to empty the trough.
This is an exact copy of the Gutr headband which lasted me 3 years before cracking at the front, where I put my fingers to pull it off. I think that pulling it off from the rear by the elastics will
stop this and get another few years out of it.
