Query: Nathan Gel Waist Pack

I absolutely love this running waist pack. It's big enough to fit my inhaler, phone, tissues, keys and a few gel packs. There is also a velcro secured compartment in the back to hold train pass and credit cards. The sizing chart is accurate. I ordered a small and it fits great. Some users complained of the long straps annoying them. If you can tuck them into the side slots it shouldn't affect you.
