This is a replacement for another similar one whose zipper broke. The woman loves him, yes, she prefers him to the other she had. Don't jump, put your phone and keys there while jogging.
Pros
I use it for my walks. It's easy to hold keys and ID, and my large phone easily fits in the adjustable compartment.
Cons
The Nathan Zipster running belt may not be breathable or able to absorb sweat effectively.
