This bag is an amazing addition when you travel. Having a smaller backpack that you can easily use for local activities during your trip is a game changer for me. That bag will easily fit a 15.6" laptop neatly (I have a Dell with the following dimension : 35,78 cm x 23,33 cm x 2,28 cm), and, if you think that bag is a bit too thin, you can even add a laptop sleeve, it will fit in there as well! A nice bottle holder on each side (both big enough so a 500ml or a 750ml bottle will be tightly held and won't fall). This bag has no padding on the back (obviously, it's made to be compact not for comfort) but got some on the straps (comfy enough) and fits into its own pocket. There's a little hoop to attached it to your bigger backpack (if you don't want to pack it inside). Overall, great buy, very happy with it.
