Affectionately known as 'Granny Knickers', this super-soft version in black organic cotton from Australia's own Mighty Good Undies is perfect for women who want smooth and comfortable all-over coverage.


- 95% certified organic and fairtrade cotton
- 5% elastane

    Organic cotton is grown using methods and materials that have a low impact on the environment. It is grown without the use of toxic and persistent pesticides and synthetic fertilizers, and the use of genetically-engineered seed is prohibited.

    Mighty Good Undies's supply chain is certified under the Global Organic Textiles Standards (GOTS) and the Fairtrade Labelling Organisation (FLO) Cotton Standard. Together, these are considered the 'gold standard' of ethical textile production across the world.

    Each standard does something slightly different. The FLO standard’s primary aim is to ensure that the farmers who grow our cotton receive a fair price for their product and have enough funds to invest in their businesses and communities. The GOTS standard ensures that only organic cotton goes into certified products, that the environmental and health impacts of cotton production are actively managed and minimised, and that workers are paid fair wages and work in safe conditions.  Both systems are based on principles of supply chain traceability.


    These undies were ethically made in India. The entire supply chain (including Mighty Good Undies) is certified under the Global Organic Textiles Standard and the Fairtrade Labelling Organisation Cotton Standard, so you can rest easy knowing that your purchase has the highest eco, ethical and sustainability credentials.
