I'm still looking for the best sweat in my eyes solution. I live in NW Florida but I guess that pretty much everyone has the heat now, we just have it longer.
My current solution (sweat band under the helmet) works but has some drawbacks: I don't like the feel of about 4 ounces of saturated terrycloth, it feels hot, and it saturates these days every 20 minutes so I have to stop, take the helmet off and wring it out. Blows the ride pace.
I tried a sweat gutter but it was worse for me. The felt band around the inside of the helmet became supersaturated and dumped it's load all at once, which somehow ended up in my eyes, blinding me.
I bought a Halo skullcap over the net but don't have it yet. Hopefully that will be a help.
Any other solutions?
It isn't a problem to me until the temps and humidity get way up there but that's what Florida will be like until October.
