Review on OPUX Premium Insulated Lunch Box Soft Leakproof School Lunch Bag For Kids, Boys, Girls Thermal Reusable Work Lunch Pail Cooler For Adult Men, Women, Office Fits 6 Cans (Heather Navy) by Katie Bobzien

This lunch bag is just the size my son was looking for so that it slips into one of his backpack pockets (reducing the risk of him leaving it somewhere if he was carrying it). He uses one small ice pack in it, and it has been very cold still at the end of the school day; therefore, the insulation seems to be working well. He has room to fit a sandwich and at least 4 snacks. The only negative input is that he would have preferred the outer pocket have a zipper like his old lunch bag had so he could put money and mini toothbrushes (to clean his braces after lunch) in it. He had to move those items to a pocket in his backpack to make sure they were secure.
