We take our coverage relating to the forces down under very seriously. From our deep dives on period underwear and menstrual cups to detailed round-ups of cotton underwear, plus-size underwear, and affordable-sexy lingerie, we’re exhaustive when it comes to matters of the vag. And, as Earth Month comes to a close, we figured it would be the perfect time to highlight one of our favorite destinations for sustainable underthings: Kent. The brand deserves to be in the spotlight for its efforts in producing a luxe lineup of fully cotton, compostable underwear. 

It’s no secret that undergarments made from natural fibers have many benefits, including airflow, breathability, and bacteria-combatting qualities. However, few panties can claim to break down and become one with the soil –– and in a mere 90 days, for that matter. Through “months of research, trials, and fittings,” according to the brand’s website, founder Stacy Grace created a pair of undies that are not only made from organic fibers but can also return to nature when they’re no longer of use. Just note that your best bet for composting these undies — and any clothes made from 100% natural materials like cotton or wool — is commercial composting. If your city doesn't have a drop-off program or only accepts food scraps, you can ship your clean, worn-out underwear to Kent to be composted.

Kent's no-frills basic styles like the brief, hipster, high-waist and thong are perfect for uncomplicated everyday day wear, and the underwear is made from the softest, most luxurious-feeling Supima cotton too. The fits also have wearers satisfied: One reviewer raved that they experienced “no ride up or slip down” while wearing the skivvies.

As far as colorways go, Kent’s focus is on neutrals (black and white), but occasionally other hues are available in small-batch, limited edition colors. The whole collection is also available in a moderate amount of sizes, from XS to 3XL.
