I purchased this on Amazon. Although it is advertised for running, I purchased for my walks. Greatest challenge is always where to carry my must haves while walking. For the price I thought I'd try this one out and wasn't disappointed.
Pros: Adjustable, comfortable and bright reflective orange color. It has a clip for your keys and two slit openings on each end making it very easy to insert your items and use earbuds. The material is comfortable and doesn't feel bulky regardless of how much I carried. I carried keys, phone, lip gloss, cash & credit card to try it out.
Cons: Due to the dual slit openings, I found myself worrying about items falling out.
