8 Sustainable Period Underwear Brands

When Aunt Flo comes a knockin’, these eco-friendly undergarments will show her who’s boss!

It’s that time of the month again, huh? No matter how light or heavy your flow is or how intense your symptoms are, we can all agree that periods aren’t fun. Oh, and don’t even get us started on the pink tax. It’s frustrating to have to buy tampons, pads, and pantiliners—and even more frustrating when you think of the negative environmental impact these items have. That’s why we love all of the brands making sustainable period underwear! If you’re unfamiliar with these undergarments, they’re designed with absorbent, breathable, and antimicrobial layers. You can wear them solo or as extra protection with other feminine hygiene products to help you experience a more eco-conscious and comfortable period.

Modibodi

Modibodi has the perfect product to support your lifestyle when Auntie Flo is in town. The brand’s sustainable period underwear line ranges from super light to maxi absorbency levels in a variety of cuts—bikinis, thongs, boyshorts, and more. Modibodi also makes period swimwear, activewear, and sleepwear. So you can keep doing the things you enjoy without worrying about leakage! Their most sustainable products are the Biodegradable Full Brief and Bikini.

Made from sustainable materials with built-in protection for a range of flows, Thinx’s portfolio of period underwear and garments will keep you comfy all day long. Each pair of absorbent panties is made with moisture-wicking, odor-controlling, and leak-resistant technology that will save you several trips to the bathroom to check in on things down South.

Tofu Tikkā Recipe

Tikkā is a northern Indian dish involving marinated protein or vegetables cooked in a tandoor, or clay oven. My version is made with marinated tofu baked on skewers in a conventional oven to mimic the traditional cooking vessel, which adds a char and smokiness to the dish. Using smoked paprika further pays tribute to the traditional cooking technique. This tikkā is best served hot with cooling mint chutneys and is delicious in lettuce wraps as well. For lettuce wraps, dice the tofu and vegetables into smaller pieces after cooking and fill the lettuce leaves just before serving.
