I have the Chub cool style food bag, this is a brilliant piece of kit with a huge main compartment and two side compartments which are large enough to take a cooker plus gas,plus two cylindrical pockets there are three external elasticated mesh pockets plus an elasticated top section.
Inside the bag there are two plates, two mugs, two knives, two forks, two spoons, two hand towels a chopping board and a bottle opener / cork screw.
And if the session set is half as good as this it will be worth every penny.
