I've tried the Polar bra and it just doesn't work for me. I'm a 36C, in case that's important to the conversation. The bra works fine as a bra, but it doesn't hold the strap against my body so it doesn't read the heart rate. Regular sports bras work fine with the chest strap. I just put the strap under like everyone mentioned. You kind of just forget it's there after a while.


Also, Polar makes two different straps. One where the whole front part is hard plastic and one where only the transmittor piece is hard. Sorry, I can't remember what's it's called and I'm being too lazy to look it up. I like the softer one.
