I am using the GUTR band for the first time this spring/summer. It's been really hot down here in the South, and it has kept the sweat out of my eyes. I've always generated a lot of sweat on my head, and it would get into my eyes when climbing hills. Nothing worse than struggling up a tough hill with both hands on the hoods, and your eyes burning and not being able to see where you are going (very dangerous). So far, I haven't had that problem this year. There is nothing to absorb sweat on this band. It just diverts it to the sides.
