In order to divide the subjects with an approximate attempt to describe the spaciousness:
She has very front 2 small compartments (eg tissues and keys).
Behind it is a subject in which can be safely stowed deodorant, cream, small brush, dental floss, mouthwash, perfume and jewelry.
Behind again is a somewhat larger compartment where a 0.5l bottle of water and 2 cases and my wallet have space. This subject is still a small zipper compartment with Mini and sewn "cellphonepocket" (which I personally but a replacement scrunchy stocked). At the back is the greatest (I think). Since even my bag with 2 table tennis Kellen + Ball fit in exactly. Also my art and Notebook (approx A5 and 3cm thick) fit in.
Rear (face-down on his back) is still a small compartment for a card or a folded piece of paper. That is me even noticed only after a few minutes of euphoria, so a good "hiding".
All bags are equipped with a zipper, so really nowhere something might fall out.
Even if it is empty backpack, it retains its shape and does not see "flabby" from. Even if it is full, it retains its shape and does not "inflated" from.
The straps are adjustable and on top of that with a zippered opening even from the top, if you wear the bag over his shoulder once.
I love that thing absolutely and would recommend to anyone who is looking for something high quality, which has not oversized lot of space, but go still absolutely sufficient storage space for working or celebrating it.
And it's definitely not enough space to reinzupacken the sweater of the partners. ;-) For me a definite plus, because something me has been "kindly" when leaving entrusted, since the bag was always so big and still had storage space.
