Most bras rely on synthetic elastic and foam that sit against breast tissue all day. This one is built entirely from GOTS certified organic Supima cotton with a plant-based elastic made from renewable tree resources instead of conventional spandex, no plastic, no synthetic coatings, no compromise. Soft, supportive, and breathable from the first wear, with a compostable afterlife when it reaches the end of its life. The bra we have been waiting for.
