I decided to write a review for this, because the one I initially bought finally died. I bought it back in 2013! I'm getting a new one today. Before this, we were using the cheapy character ones for my son, with the white lining inside. I had to keep replacing them, because the lining would crack and tear, and the insulation would be exposed. The insulation would quickly get stained and yellow, and there was no way to clean it at that point. Picked out this one, and it's been great! It lasted 4 years for us, and it was really used a lot. My son used it at school from ages 6-10, several times a week... it's been shoved into book bags, dragged on the ground, and spilled in lots. I've put it in the washer tons of times and it held up. There was very slight pilling on the top flap, but nothing really noticeable, and nothing that made the bag unusable. The only reason I finally had to replace it was because one of the zipper handles broke. It was still okay to use temporarily because there's 2, but I wanted to get a new one in case the other one broke too, which would leave us no way to close it. I was surprised with how clean I was able to keep this bag. I was fully expecting to replace it sooner, not because anything had broken, but because it was getting dingy and gross. It never got gross! For every day freshening up, I would wipe it down inside with a disinfectant wipe, and leave it open to dry. For bigger messes, I threw it right into the washing machine with other laundry, and hung it up to air dry. The color wasn't as bright anymore, but had that zipper not finally broken, we'd still be using this. The size of this bag is great, too. My son is not just a "sandwich and crackers" kind of kid, he likes a variety of foods. Which means I needed to fit a variety of containers and sometimes up to 2 ice packs in there. For all the years we've had this, I can't remember a time where I was not able to fit everything. I'm replacing ours after 4 years, but I'm sure this will last a lot longer for others. As I said, our bag really took a beating, and I'm pleased I got this many years out of it. I'm reordering it right now, I have no need to look for a different brand.
