Cloth pads or otherwise known as Mama Cloth, are basically reusable/ washable pads that you use during your menstrual period. Hannahpad was founded by a man whose partner suffered severely due to disposable products. They are the first company internationally who manufactured organic Cotton Pads, and started operating in 2005. These pads are made up of cotton layers, waterproofed fabric at the back to prevent leakage. They come with wings that snap underneath your underwear and stays therefore in place, permitting that your underwear fits snug. Hannahpad comes in different sizes, aiding absorption. So a Pantyliner would be for very light bleeding and the Super Ultra Overnight would be long pads for very heavy bleeding. See sizes on the product page.
