I haven't had a backpack since I was a Scout.  I went on a trip to SFO and needed something better than a cloth bag with handles.  This worked great - I ended up hauling a lot of stuff from the grocery etc and it handled it all.

It's got three zippered pockets: large, medium, and small.  The mesh side pockets are too large to comfortably handle a pint water bottle.  Construction is adequate.  Price was great - $9.99 with free Amazon Prime shipping.
