Autoform Explorer 380
Price: £194.95 Capacity: 380 litres
An attractive swooping design from one of Sweden's major roof box manufacturers. Unfortunately, the aerodynamic, low-profile, shape meant our biggest suitcase wouldn't fit in. Still, the quality of the case is excellent and the ABS plastic used is both thick and sturdy. Gas struts are used to push and hold the lid open, and although only the right-hand side opens, innovative clamps mean one-man fitting is possible, albeit rather fiddly.
