Review on PYFK Running Hydration Bottle Reflective by Mark Sutovsky

I have to say I was really skeptical when I bought this item. I've never seen a running belt/backpack that didn't look extremely bulky. But after being dissatisfied with hydration bladders and backpacks, I decided to give it a try. It arrived today and I took it for a 4 mile run in the park. It took me a mile or two to figure out how tight to make it and where to place the water bottle part, but once I set it up so the water was in my lower back it was great. He doesn't actually move at all. It fits perfectly in my CamelBak Eddy water bottle. Only criticism is that the strap is quite long. Not sure about my waist size but probably around 30 inches. I had an extra strap that didn't have Velcro. I would buy a smaller size if they made it.
