Good bag, exactly as measured -- it's a medium sized bag that can fit a towel, sneakers, your clothes, etc.  I use it to go the gym every morning (so it has to carry all my stuff), and it also fits into the top shelf of the locker.  There isn't any lining inside, and there are no extra pockets except for the main compartment and the side compartment.  Good price for the product, and the color is nice as well.
