This is a heavy duty rubber boot liner mat from Autochoice, part number BM52, made to fit Citroen C1, C2, and C3 models – but it's a universal design, so it'll work in a lot of small hatches with some trimming or just dropping it in.
It's made of tough black rubber that's waterproof, so spills, mud, or wet gear won't soak through to your carpet.
The material also has anti-slip properties, so your groceries or tools won't slide around every time you turn a corner.
Easy to clean – just pull it out and hose it down.
It weighs about 2 kg, so it's thick enough to handle heavy loads without tearing.
