Travel bags with 2 internal pockets

≥ 2 inside pockets

— the bag has several (two or more) internal pockets.

For the inner pockets themselves, see the relevant paragraph. And the presence of several such pockets allows, firstly, to carry more things than in one pocket, and secondly, to sort and organize the contents. For example, in one pocket you can put documents that are not needed during the trip, in the other — small souvenirs.
