Review on Running Expandable Resistant Climbing Smartphones by Michael Hall

Update: Product quality may not be very good. I say that because it keeps loosening and twisting during use. I bought this style because when I had another brand of the same style a few years ago it worked great with lots of use but I lost it when moving. This brand is good for all of the reasons mentioned in my original review, except that it doesn't stay flat and tight to the body as intended. My friend who trains with me has the same problem. I suspect if you just put the key fob and driver's license in it will be fine, but it won't carry weight like a phone and sometimes a small travel purse. Original: I like that the pockets expand. with whatever I put in it. It has two pockets so I never have to worry about losing things when I'm fiddling with others while hiking. I put my keys in a bag and never open it on a hike. Another pocket holds my phone, which I usually take out at least once to check the workout app, take a picture, or read a message. My girlfriend squeezes a small disposable water bottle into the larger of the two pockets, but I think she would be better off with a product made specifically for water bottles as she has a bit of a hard time getting it out and replacing it. This product is more for storing multiple valuable items. It sits as flat as you stuff it, meaning minimal bulk and no flapping.
