I was expecting the bag to be a little bigger but to be honest, I am not mad about it after wearing the bag out. The bag can fit a 125 ml water bottle, a wallet, and a phone EASILY with room to spare. The bag is also very sturdy and does not deflate when you have nothing in the bag. The cookie's edge did bent during shipping but it is fixable. I HIGHLY RECOMMEND this bag, especially with the sale price!
