Insulated canvas with a zip closure, so food and drink stay cool through the school or work day rather than going warm by eleven o'clock. The interior takes a full lunch plus a drink and a snack box without anything being squashed.

The print covers the front panel. Beyond looking better than a plain bag, a distinctive print is the difference between finding yours instantly and going through six identical ones on a shelf, which is the entire problem a primary school cloakroom presents.

The same prints run across backpacks, water bottles and pencil cases, so the whole kit can match for September. Designed in the UK and made to order rather than pulled off a shelf. Every order plants a tree.
