I recently got a chance to try out some FlipBelts! They are really well-made, and solve the problem of having NO pockets on any cute workout clothes. They were very comfortable, and held my phone well (with the headphones plugged in), and it had a little fob to attach my keys to. Very nice for a long walk with our pups, or great for heading to yoga class. Not bulky at all!
