It's been, like, 90% humidity in the morning when I commute to work, and I'm a heavy sweater. Sexy, I know. I use one of those headsweats things or a cycling cap under my helmet, which helps, but not enough to keep the sweat from dripping off my forehead directly onto my sunglasses. Does anybody else have this problem? Anything I can do about it? Do those sweat gutter things work? Thanks for any advice.
