A while ago, I went into the local Performance to buy a pair of black shorts. For $10 more I bought my first pair of bibs. They are the Performance brand with white mesh up top. I've worn them on two centuries now, and they are nice and comfortable. I didn't wear undershirts on either occasion, and the suspenders did not make their presence felt. they do feel a bit warmer in full sun, though....

I like 'em.
