Mostly on a whim, because it was a handmedown that just started fitting. Before that its always been plain single color Garneau shirts and shorts (no bibs). While I did feel a bit like a poseur with all those ads all over my body, I have to say I really loved the bibs. I actually wore a windbreaker because I'm a wimp and it was cold to me, so hard to say how the shirt was (other than soaked under the jacket...maybe it was modesty and wimpiness...).
Overall, I liked it. I think these bib things have something to them. I have an cheap pair of Casteli cycling shorts that are now (thankfully) too big and roll down all the time and make me crazy.
Anyway, that's it. I had to share with someone.
