I only ride in normal clothes. I also like to push hard most of the time, and go for a longer ride before or after work. With the weather getting warmer, I have been getting swamp ass. I don't really care, other than the fact that I'm beginning to get a little sweat stain on my ass. Today I got my first one on jeans, before this it was only happening with khakis.
What can I do to prevent this? I'd rather not get biking shorts and have to change, since that would be a major time suck. What about the biking underwear that I've seen at REI, would those help?
