You do your best to pick out ethical clothing made with eco-friendly materials, but have you given any thought to your underwear? Yep, that’s right. Eco-friendly underwear is just as important for your skin as it is for the planet’s health.

We’ve all been there, rummaging through the underwear drawer for that perfect pair of skivvies. But have you ever wondered about the environmental impact of your favorite go-to undies? After all, the fashion industry hasn’t always had the best track record when it comes to sustainability.

From organic cotton briefs that are gentle on the earth and your skin and recycled polyester panties that give plastic waste a new lease on life to classic neutral hues and funky patterns that add a splash of personality to your wardrobe, we’re exploring the entire spectrum of sustainable underwear brands. We’ll also take a look at why it’s so important to make the switch.

Eco-friendly underwear is your everyday secret weapon for feeling comfy, confident, and guilt-free. So let’s take a look at the best options for the whole family.
