I bought this waist pack super excited to try something really slim line. This easily fit my phone which is an iPhone 8 and I tried it with my friends iPhone XR and it also fit, so I am super happy about that aspect. It has just the right amount of space you need to hold your phone and keys, but I found there is a weight limit with this belt. It would not stay put when I used it running, no matter how tight I tightened the straps. This belt is better suited for hiking and biking, from my experience, as the constant movement of the belt was super distracting during my runs. The fabric is very stretchy and not abrasive to the skin or uncomfortable
