Review on TRIWONDER Hydration Pack Backpack 5L: Ultimate Performance for Marathon Running, Cycling, and More! by Roberto Manzer

I've run 10 marathons including the Boston Marathon. I mention this to say that I was looking for a backpack that doesn't bother me at all while running as I'm a very competitive runner. After reviewing various Revain kits, I settled on this one. I am very happy with it. I've already run a half marathon on it and with this photo I'm going to run a marathon in 2 weeks. I have 1.5L because I feel it will improve my performance with my mileage. The package goes well with all my gel packs. There is a back pocket where I keep most of them. I am very happy with the front pockets on the shoulder straps of the backpack. I keep the gel pack on the front right strap and the left strap has enough space for my Galaxy S7 phone. The water hose doesn't seem to get in the way as long as I thread it through the front clamps. For reference, I'm 5 7 and weigh 130 pounds. I can attach the backpack tightly to my body so it doesn't bounce on my back. There is ventilation on the back of the backpack so that I don't get too hot with the backpack. I would recommend this pack to other runners as I am very happy with it. It was definitely very similar to the Nathan pack I've seen for a fraction of the price.
