Atera Odyssey 800
Price: £194.95 Capacity: 420 litres
Despite weighing only 15kg, the Atera can hold up to 80kg - if your car can take the strain. Easy-to-attach clamps use sliders instead of drilled holes in the base, with U-bolts pushing into fittings within the box. And simply turning a lever locks each of the sliders in place and tightens the bolts.
