Perhaps I'm the vain one. All I'm saying is I don't want to show up to class in wet spandex, with wet spandex underneath and soaking through my regular pants, or having to change before actually going in class. And for the price I would get these--around $65--it doesn't pain me to have another pair of jeans I can wear around.
I'm not anti-lycra. There is a time and a place for it. Huge distance ride? Sure. However, in my opinion, commuting to and from school in the rain is not one of them.
