Review on 📱 Gear Beast Running Backpack: Lightweight Vest & Phone Holder for Jogging, Hiking, and Cycling - Black, Compatible with Most Smartphones by David Butterfield

is MUCH better and more functional than I thought. It's a little tricky to get it right, but I've found it's best to adjust it to fit just above the shoulder blades and just below the neckline. He used to not jump much at all. I was very concerned that it would be springy and rub against my back, but it stayed stable throughout the 6 mile run. It has space for a Galaxy Note 8 cell phone and an ID card and even a couple of energy cubes. I don't use wired headphones so I'm not sure how well the cable holes work. Though it looks like they're doing fine. I think the design could be improved with some lighting or even more reflective elements for safety. If everything was reflective, I could even ditch my safety vest and just use that. I think they might try this in a future version.
