These bags actually have way more space tgen I expected. They have a lining to keep either your stuff hot or cold it helps keep in either. I like how it has a pocket outside so u can put silverware or dishes in. I used this and put 8 20 0z my dews in it. I've got this for all my grandchildren and children. And now I have adults asking where I got this lunch bag. So another two thumbs up. Love my new lunch bag
