Review on Water Bottle Running Belt - Waist Pack with Water Resistant Pouch for iPhone, Samsung, 🏃 Android - Adjustable Belt, 10oz Bottles - Ideal for Running, Hiking, Cycling, with Race Number Attachment by Andrew Grant

I am happy with my purchase. I ordered it to store my phone and keys. I figured water bottles might be good for long runs. As soon as I received that, I washed the bottles, refilled them and went jogging. I thought I was going to carry it on my back, but when I started walking it was bouncing all over the place. I flipped it face down and continued, no problem, no jumping. I could have maybe tightened the waist belt but then didn't want to mess with it and was surprised by the convenience of the belt on the front. Water bottles have much better access when carried from the front. If the belt is too big for you, it would be easy to change the belt to be much smaller.
