and is easily adjustable. It is comfortable, weighs nothing and has no bulk at all, which I also appreciate. I can easily slip my car key behind my phone in the pocket as well...just the key, mind you..nothing else.
That being said, while I know that I have not stretched it out yet....it doesn't fit me very well anymore. It is definitely built for a larger woman or a man's body. So, if you fit this description, by all means, purchase it. But if you are small-medium build (woman), pass it on to your husband :)
