I LOVE these cool-bags from Anorak, they are cool and chic. Top and side opening with double zip for easy access.
It's waterproof, durable and the rear straps cleverly hold your rolled up Anorak picnic blanket in place (sold separately).
It has a 20 litre capacity, with 5 hours of insulation so plenty of time to get to the beach before feeling peckish.
Good size to fit in your Tupperware 40cm x 34cm x 14cm
Material: Polyester outer, PEVA inner
