This good-sized cooler knocks spots off other bags. Open the central zip - the matching tags make it easier - and you'll find plenty of room for all your picnic food. Being wider than deeper it's also easier to find the food.
The insulated materials will also keep it nicely chilled. The matching stripy carry strap is adjustable, so you can wear it over your shoulder or at arm's length. The strap's also detachable.
