I absolutely love this running belt and I know I will use it until it breaks or something. It is adjustable, super comfortable to wear and even sweat proof! I own an iPhone 6S Plus so I was looking for something bigger where I could fit it without issues and this running belt holds it perfectly while leaving me space for other items.
The main pocket divides pretty much in half lenght and has two smaller pockets in the divider so I can usually have my phone in the front and in the back keep some money, cards and even a snack.
It has two pockets; one on each side of the main pocket and there I usually store my ID and the second one has a hook for a key it also came with an extra hook you can hang from it to keep a water bottle (I don't use it because I don't want the extra weight but it's an option). It also has a hole for your headphones cable for easier moving. You can adjust it to fit snug and not have any bounce issues.
I have already washed mine in the washer without any issues and it's definitely a keeper!
