Otherwise it has the sturdy air and very well made, a smooth coating so that rain does not penetrate inside, but given the thickness of the inner pockets (good padding), I think that there is no risk .
This bag has several compartments (what I needed to put my personal leaves, snacks, portable, small first aid kit etc ...).
Also good padding on the back of the bag to make it more pleasing to our backs.
I'm very happy, closures work very well without stuck, now the months and years will tell me if it is really TOP ...
I recommend it because its size is neither too small nor too large.
