What's one of the most underappreciated underpinnings? Period underwear, in our humble opinion. It's nice to have another option for that time of the month aside from tampons, pads, and menstrual cups. You can choose whatever works best for you and your lifestyle when it comes to period-care products these days, but in our opinion, period panties are the most comfortable option out there. Unlike other menstruation products that either require uncomfortable manual insertion or aren't fully leak-proof, period panties allow you to free-bleed without having to make adjustments every few hours. Plus, they're a far more sustainable option compared to the non-biodegradable products that dominate the feminine-care space.

However, if you're unsure whether this is the right option for your cycle, you'll want to keep reading. Ahead, we're addressing a few common questions surrounding period panties to help you discern if this product will be a good fit for you. We're also including a roundup of the best period panties on the market based on reviews, functionality, and brand recognition. Rest assured this underwear will make that time of the month much better.

About Period Underwear

How does period underwear work?

If you're unfamiliar with period underwear, its name pretty much speaks for itself. It's underwear designed to soak up menstrual fluid with multiple layers of fabric. Like tampons and pads, the underwear has different absorbencies and fits—some are meant for your heavier days, while others can be worn on the lighter last days of your period. While this underpinning is quite technical in its design, you'll be happy to know that just like any other underwear, it's available in various cuts—e.g., briefs, bikinis, and thongs—ensuring you can find a style that best suits your needs.

How long does period underwear last?

Although period panties are reusable, like other undergarments, they don't last forever. The lifespan of this product depends upon the quality of the brand you've bought, how frequently you wear them, and how well you care for them. The latter is extremely important, as how you wash these panties can affect how effective they are long-term (which we'll get into a little later). That being said, most experts say that these panties usually last two years if they're well-made and well-maintained. However, it's vital that you continuously check the state of these panties, as, like any menstrual product, they can impact your day-to-day life. If you begin to notice wear and tear or find that you're spotting on clothing during your period, it's a sign to replace them.

How do you wash period underwear?

One of the best things about period panties is that they are reusable, unlike other menstruation products. However, you'll want to wash them in a specific way to ensure maximum hygiene. Typically, it's recommended that after wearing them, you should rinse them in cold water to remove excess blood, then wash them in your regular laundry. Most underwear brands have tips for maximizing the lifespan of these panties. However, for most types, it's best to avoid using hot water and harsh cleaning products, as they can damage the absorbent layers.

Does period underwear smell?

Like any other absorbent menstrual product, period panties can develop a slight odor if not properly cleaned after use. However, if you properly wash your period panties (as explained above), you shouldn't have issues with the garment smelling. We recommend that you not only hand-wash your panties before throwing them into the laundry but also consider air-drying them in the sunlight to help eliminate any remaining odors. If that doesn't work, it can be a telltale sign that it's time to replace your period panties.
