I LOVE this backpack, it is the perfect size for a small day use pack/purse.  I plan on using it for a little of both.  It is not large at all, do not think of this as a school backpack unless it is for a small child and all they are carrying is lunch and some extras, large books will not fit.  Having said that, it will fit a full sized camera, along with a light jacket and water bottle, plus pockets for wallet, keys,  phone and other goodies.
 It's great for travel, very easy to carry, unlike a full sized backpack that would completely take up your whole lap or a seat, this is 1/3 the size.  The colors are beautiful and the quality is very well made. No regrets.
