Rab are having "bags for life" made from offcuts of rucksack fabric that would otherwise end up in landfill. They come in random colours, two sizes, and being rather stronger than your average bag for life, useful for gear storage, rope lugging and, of course, your weekly shop. This is the Standard size.
And Rab donate at least 50 pence from each sale to Dukes Barn, a UK charity providing outdoor education for all sorts of disadvantaged children.
