Review on 👜 Waisted Wonder: The Ultimate Unfanny-Fanny Pack Waist Pack by Rosalio Zavala

It works well and yes the zipper is the reason I chose this option over others. Take off more than put on. It is elegant under a shirt and can be used for many other purposes besides running when you need something to hold and don't want to carry a large bag. It catches sweat as you run, but that's to be expected. It's probably worth putting the phone in a pocket or something else to protect it from moisture.
