I read that alot of you are needing an armband for jogging. I have the Xtrememac sportswrap. I bought it before the nike+ kit came out. So it does not fit, but it's made of neoprene. So I just made a small cut on the bottom for the sensor to fit through. I've logged 11 runs I think so far with no problems at all. I wear mine upside down since the earphone jack is on the bottom(keeps it from getting pulled too much, or getting under my elbow), plus this way to skip to the next song i just reach up and click right, instead of having to look at it and make sure my finger is in the right spot. Just make sure your cut doesn't connect to the hole for the earphone jack, and make sure it's slightly smaller than the jack for the sensor, neoprene stretches ofcourse. I connect the sensor then slip it into the jack. It has windows for the wheel and the screen, hope this helps.
