Backpacks with bottle pocket

 

— a pocket of this type is usually located on the side and does not have a clasp — it is open at the top, which allows you to conveniently place inside a bottle or other object of a similar shape (umbrella, rolled up magazine) or small sizes (pack of wet wipes, flashlight, etc.) . Such pockets are often made in pairs, on both sides of the backpack, and both dense fabric and mesh can be used as a material for them; the fixation is provided by an elastic band in the upper part of the pocket.
