Backpack just space, surpassed all expectations!) it is sewn perfectly, nothing sticks out anywhere, but I assume that the straps can tear off after a while. but this is not a fact) there is no partition inside, but it is not needed in principle. three internal pockets: on the lock and 2 under the trifles and phone)) roomy, 2 balconies for 2.5L will fit exactly: D is very happy with the purchase, thanks to the store for the goods. I recommend to everyone))
