Review on ENGYEN Running Workout Hydration Runners Sports & Fitness and Running by Tyler Owens

Very comfortable fit, stays in place and does not wobble with movement. The color is nice and bright (mine is pink) so this helps increase visibility when used while walking outdoors. Sizing is easy to adjust, however there are a few minor imperfections in fit and size. These issues don't really affect functionality negatively for me, but may be useful for others. 1) The main waistband is only elastic in part while it is mostly inelastic. It has an elasticated strap under the main strap in a small section (about 3 inches long) that allows it to be adjusted by stretching slightly for breathing and movement. But when the strap is properly adjusted to allow room for stretch, the main strap sticks out a bit when the elastic is unstretched. It doesn't bother me, but for those who require it to fit snugly against their body without the strap parts protruding, it might be a bit of a concern. 2) There are 2 zippered pockets but both are quite small. I have a medium sized phone (maybe even smaller - Galaxy S10E with thin body) and it hardly fits in a big bag. The material doesn't stretch, so there's no wiggle room to adjust if it doesn't fit. If I had to carry my keys in a smaller bag, the extra bulge from the keys could make my phone no longer fit in the larger bag. Overall I am very happy with this bag and look forward to using it on my outdoor workouts.
