When your time of the month comes unexpectedly and you have to rush to the store, tampons, pads and panty liners are the majority of what you traditionally find when looking in the menstrual hygiene aisle. Recently, period underwear has risen in popularity to prevent the unnecessary waste that comes from using these products.

Period panties are a newer form of menstrual care that can both replace the need for disposable hygiene products and be a solution for preventing messy leaks. They're an ecologically smart alternative to single-use period products and a great long-term investment for those who want a more comfortable and easier menstrual solution.

Every person and menstrual cycle is unique. In this article, we'll explain the benefits of period underwear and help you find what type of underwear is perfect for you.

Why Switch to Period Underwear?

Designed to feel and look like regular underwear, period panties are a reusable menstrual product made to be worn longer than single-use period products. These undies can hold the equivalent of anything from one to five full-sized regular tampons.

Traditional tampons and pads are recommended by the FDA to only be worn for four to eight hours because of the risk of toxic shock syndrome or a yeast infection. When used correctly, period panties can be worn for up to 24 hours without leaks, odors or discomfort.

Not only do they have to be changed less often, but they also come in handy when you're expecting your cycle to start and you want to be prepared. Instead of a late-night run to the drugstore, you can count on having your washable, re-wearable panties ready to go when you need them most.

Besides the physical comfort and ease of period panties, this underwear is a great solution to the high number of menstrual products ending up in landfills. The average person who menstruates uses around 11,000 disposable period products in their lifetime. And it's not just the products themselves — there's usually an extra layer or two of plastic wrapped around the items for sanitation that gets discarded.

Although menstrual hygiene products are all but necessary, the waste that comes with them doesn't have to be. Period panties can be reused for up to 2 years, making them a viable solution compared to traditional hygiene products.

Caring for Your Period Panties

Once you're done with your period underwear for the day, rinse them with cold water. If the period underwear is machine-washable (some are not, so be sure to check your pair), place them in a washable mesh bag and throw them on a delicate or gentle cycle with cold water. Try to use a mild laundry detergent and never use softener or bleach, since these can deteriorate the absorbency layers.

If you want to help your period underwear last even longer, try to hand-wash them to help the fabric's integrity. Once your underwear is washed, make sure to always hang them to dry (putting them in the dryer can shrink and distort the materials).

Period panties are usually designed to be stain-resistant and odor-free, but if you're looking for extra care, you can always use natural remedies such as applying white vinegar or lemon juice directly to the desired area before washing.

Frequently Asked Questions: Period Underwear

Does period underwear really work?

Yes, period underwear really works. These products are made with multiple protective layers to replace traditional single-use menstrual products like tampons, liners and pads and to make you more comfortable during your menstrual cycle. They can be worn during the day, overnight or as backup protection.

Can you wear period underwear all day?

Much like tampons and pads, how long you can wear menstrual underwear depends on the product's absorbency level and your flow. For lighter days, you can typically wear a single pair for a full day. When it comes to heavier days, make sure to use high-absorbency panties to get the most out of each pair and prevent the need to change mid-day.

Can you leak with period underwear?

Like all menstrual products, period panties have a max absorbency amount but usually can withstand much more than the average tampon or pad. Most period panties hold at least two times more than tampons. Some period underwear, such as Proof's Leakproof Hipster Underwear, contains barriers to prevent leaking even if the absorbent layer is completely full.

Can you wear period underwear without a pad?

Period underwear can easily be worn alone. Just ensure you purchase the correct absorbency level according to your flow. Made with moisture-wicking barriers, absorbency layers and leak-proof seals, you can count on period panties to keep you comfortable and protected without the bulky feeling of a pad. However, you can also use them alongside your usual menstrual products if desired.
