Bummis are a Great Grandmother of cloth nappies. They have been around since 1980 when modern cloth alternatives to the flat terry were just starting to appear. They are from the US/Canada and are made there too. So if you want a cloth nappy system that you know has been perfected, well tested and made by ethical working conditions, then Bummis is the choice. They focus on great fitting covers and organic cotton prefolds, not to mention their swim nappies as well.
