Today Nutricia delivered the Rumble Trunk designed to take drinks and equipment when you fly. As you can see it is quite large, measuring 86cm (34in) long by 43cm (17in) wide by 36cm (14in) deep.
It has a handle at the top with two wheels on the base for easier carrying. There is a hole midway on each side presumably to take a padlock, but I would want to add a strap in case one of the yellow securing clips got caught on something.
I am just trying to imagine how heavy it would be if crammed with drinks, and if the airline would levy excess baggage charges.
