Made from organic cotton canvas with a water resistant polyester lining, this insulated lunch bag is perfect for storing lunch and snacks! The durable and lightweight design is easy to spot clean and is machine washable! The Velcro closure is easy and secure ideal for both adults and children, keeping your lunch fresh and safe all day! It also comes with a handy inner ID card holder! This is made of cotton and polyester (I don't think 100% cotton ones exist) so please make sure if you ever wash to put in a Guppyfriend wash bag to catch any microfibers! WHY I STOCK THIS As I can't find any alternatives that is cotton I decided to stock this hat as I know it's made by a great company, who deliver to me plastic free which I then send to you plastic free. This way it's saving an alternative being bought elsewhere which would be the same material but potentially come in a plastic bag with a plastic tag.
