It's good that this product comes with 2l backpack which is easy to carry for a long period of time, if you're running your half marathon limits, what I'm not satisfied is that there should be a gel carrier, or a mobile phone carrier, in a front Side, where one can easily keep their phones and talk and walk during workout sessions, my only concern is that if there were gel carrier,phone carrier in front,which is not there, otherwise it's good and easy,lightweight to carry,and one more thing I think it's not water proof or water resistant, because I did my 22k and 19k with this product in a rain which almost my fruits and cash were not found dry after running session...
