Bob the bucket bag is made from discarded boat covers . Boat covers last for a relatively short period of time before the UV damages them . They are then condemned to landfill. Often large swathes of the cover are perfectly fine to repurpose . 
The Burnham Overy Boathouse Bucket bag is ideal for keeping in the boot of the car to dump those muddy walking boots and welly boots in after a long wintery (or summertime!) creek walk .
