I typically don't leave reviews, especially unhappy ones, but I was not at all satisfied with this purchase.  One of the side pocket snaps had loose stitching and came off within 5 minutes of opening the package.  Straps dig in at the point where your arm meets the shoulder.  Extra spotted canvas comes out at a point on the straps where it should curve.  I have bruises on both upper arms where it dug in. Overall design isn't great.  It is difficult to get in and out of the backpack.  I wish I hadn't purchased this and just used a bag I already own.
