I would love to see somebody try to put antiperspirant all over their back and shoulder. Y'know, it
just might work.
whats worse than back sweat is when you dont sweat at all when riding, but when you go inside, you start complaining that its hot and then you start sweating bricks. makes you look very nervous and sketchy, like you are about to rob a place.
I get this every day when I ride to classes in those old campus buildings with no A/C whatsoever. As soon as that wind is gone it just comes out everywhere. I think it has to do with these mid-70's temperatures... then , of course, you get self conscious about it and sweat some more.
