Hopefully this makes sense and I thought I checked the bag when I got it. But when I went to use it I noticed a small section where the bottom meets the side piece (where the stitching is in the interior) had come apart from the side of the bag and if you lift the bag up you could see a small hole...the weird part I could not see anything on the outside. So I sent it back for an exchange..the bottom piece seems to come up along the side of the bag a little bit and then stitched.
Hope you get a perfect new one!
