What is the estimate of books and binders that this bag will hold?
MICAH G Without a laptop, I think it holds 4-5 average textbooks. There are latches on the sides which you can unclip to allow the backpack to expand more.
KARTIKEYA S I bought this bag mainly for its storage capacity. The three compartments can accommodate up to 15 books (I've done more too, long as you are ready to bear the load!). My typical load for this bag was a laptop, 5-6 books and a few folders, and an overnight change of clothes along with spectacle case, mp3 player, coins, deodorant, chargers for laptop and phone, and many other small items.
Great quality, hangs well on the back, and has more storage than any other bag I looked at within the price range.
