This works great for storing my cell phone while walking/running, and listening to podcasts/music via Bluetooth. If I put my cell phone in my pants pocket, the Bluetooth breaks up frequently. Even while holding my phone in my hand it still breaks up when at my side, so I have to keep it in front of me. This vest solves the problem. No Bluetooth breakups.
The only reason I don't give 5 stars is because it is somewhat snug, to the point of being uncomfortable when I first put it on. I adjusted the straps to the loosest setting, and it is fine now, but if I were much bigger I would find it very uncomfortable. For reference I am 6 ft 2 in and 205 lbs. , so if you are much bigger than me, you mimght want to pass this up.
Overall I am very satisfied with this vest.
