Review on Running Hydration Bottles Marathon Adjustable by Devon Dober

In short, 10 oz bottles are light and fit well in the pocket thanks to a small elastic band to keep them from falling. The bottles are also leak proof as they have a stopper. The elastic band is very well designed and well adjustable. The case is a decent size and easily fits my Samsung Galaxy Note 3 with a fairly bulky case. I also tried installing 2 phones, my note 3 and also my girlfriend's note 5, with the mophie power case - it was very tight but was able to fit.
