Nipple Guards for Runners

The New York Post had an article yesterday on gadgets that help runners. With the NY marathon coming up its almost an expected use of newsprint. Fancy sneakers and watches aren't much of a surprise, but Nip Guards were. I've never thought about chaffing of that sort but I suppose it can be extremely painful. And at $9 it seems like a bargain, but I have to wonder if two strategically placed Band-Aids couldn't do the same job.
