You read that right; these organic cotton panties are 100 percent compostable and will break down in soil after just 90 days. Don’t let that scare you into thinking they’ll fall apart quickly. According to reviews, they wear and wash incredibly well (plus, it’s only after they’ve been placed into a compost container that the fibers will be encouraged to break down). In another nod to sustainability, only black and white are included in Kent’s core collection and all other colors are manufactured in small, limited batches to minimize excess waste. One reviewer writes, “[Kent undies] are incredibly comfortable and breathable all day long. They look beautiful on. [The company has] wonderful customer support. Plus, it’s run by women for women and is environmentally friendly from beginning to end. What’s not to love?!”
