While buying clothing second-hand is a great way to minimize impact on the environment, most of us are not willing to do that with our underwear. We want our drawers to be new, but we also want to ensure they are sustainable. So before we can look at the best brands, first we have to ask what is sustainable underwear?

The most sustainable underwear brands are implementing progressive business practices to minimize their impact on the planet and people. They use eco-friendly materials like GOTS certified cotton, merino wool, bamboo and even upcycled material. They are also taking measures to ensure that their employees are treated fairly and provide transparency in their manufacturing processes.
