I grew up hearing that thongs are not good for, ahem, down there. I don't really want to get into details but it has something to do with a lethal combo of yeast, and moisture. This meant sleeping and working out in a thong were a big no-no.
NiteSweatz ($16.00) thong is for anyone who has feared the thong while working out. The silky blend of fabrics coupled with moisture wicking and anti-microbial properties, make these undies pretty fashionable while still being totally functional. This means you can still be pantyline free, even at the gym. Buy one (or three) today from NiteSweatz.com.
