I was used to the old fashion waist packs so I was surprised when this one had a elastic waist strap. It is quite comfortable even though it is a snug fit. I actually put mine under my shirt so I can carry my phone, credit cards, and some money while I'm out for my walk. I only walk during the day, so I dont need the reflective markings as much. However, I am getting ready for a trip to Disney World where I'll be out all day and night so I'll get a lot more use out of that part. My family will be able to see me. lol It holds my phone snuggly and there is no flopping around like the only ones I used to have.
