Anybody have any experience with heart rate monitor bras? Either the Polar or the Numetrex? I'm thinking of getting one and am leaning towards the Numetrex because the transmitter fibers are woven into the bra. I get tired of wearing the chest strap and would love to find an alternative. My main concerns are:

1) Does it work?
2) Does the bra provide enough support?
3) Does the bra dry adequately from the swim?

Any information would be helpful!

Thanks,

Joanna
