Looking and feeling like real underwear, Thinx’s line of period panties are washable, reusable, and incredibly absorbent.

    Featuring an extra layer of innovative lining material that absorbs as much liquid as five tampons, Thinx underwear can be worn as a total replacement to tampons and pads, can be worn at night, and can even be worn in addition to other products should you choose. Here’s the best part: they aren’t bulky, they’re completely breathable, and they neutralize odor. They’re also incredibly easy to clean – simply throw them in with your regular wash and hang dry.

    • Affordable
    • Comfortable to wear
    • Care and cleaning is a more involved process
    • Sizing runs big
    • Sizing isn't as inclusive as other brands

    Much like the overnight options from Thinx, Modibodi, and Knix, this affordable style from Goat Union is incredibly absorbent and will keep you protected from unwanted leaks while you sleep. Adhering to the three R’s – reduce, replace, and reuse – these washable and reusable period panties are an ideal alternative to pads, tampons, and menstrual cups. 

    Made from a comfortable blend of bamboo viscose, spandex, and cotton, these full-coverage briefs feature four layers of high-performing material, are moisture-wicking, and absorb as much liquid as three tampons. Perfect for all flow types, these panties are also great for postpartum recovery and incontinence uses, too.

    While the manufacturer boasts an easy cleaning process, there’s a little more care and handling involved. Simply rinse before placing it in the washing machine, gentle cycle only, and hang dry when done. Goat Union also recommends that you avoid the dryer and never use bleach or fabric softener.

Available in a variety of sizes, these hipster panties offer maximum leak protection from rear to front and have an absorbent midsection and layer.

    A popular seller on Amazon, Bambody’s period underwear is available in a variety of colors and is even sold in bundles if you feel like picking up a few pairs at once. Information is limited on whether these panties replace tampons and pads altogether, but the brand boasts that these are the “best back-ups in town.”

    Some reviewers did have issues with stains, even after washing, while others commented that these are not the best options for heavier flows. However, if you’re new to period panties, these are an affordable option worth considering and testing the waters with. Additional Bambody styles are available by clicking here.

  7. 7. Hesta Organic Cotton Period Panties (3-Pack)

    • Affordable multi-pack
    • Made with certified organic cotton for an uber comfortable fit
    • Per several reviewers: they wash well
    • Must wear in addition to pads, tampons, or menstrual cups

    • Not as leak free as other brands

    If you’re looking for comfortable period panties, this certified organic cotton option from Hesta is an excellent choice. With hundreds of 5-star reviews, this popular seller offers full coverage and protection from unwanted leaks. While you must wear them in addition to pads, tampons, or menstrual cups, these do provide comfort and ease of mind so that you can live your life without fear of any unsightly accidents.

    Ideal for menstrual cycles as well as postpartum recovery, this is a solid purchase for anyone looking for an affordable multi-pack. The one downside is that this underwear must be worn with pads or tampons, so if you’re looking for an option that replaces traditional menstrual products, we’d suggest another style.

Why Buy Period Underwear?

Hearing "period underwear" raises an eyebrow, right? We get it. The term is often used to describe those stained "throw-away" undergarments you wear just in case anything leaks through. Not just that, but if you're an exclusive user of tampons or pads, anything other than traditional menstrual products seems a little out there. But, period underwear is actually more popular than you think. 

While the concept for period underwear has been around since the 1980s, the sleek and sexy silhouettes we see today from companies like Thinx, Knix, and Modibodi have only hit the market within the last ten years. Offering women of all ages an alternative to traditional menstrual products, there are a number of benefits to consider if you're looking to switch up your monthly maintenance plan:


It's no secret that traditional menstrual products like tampons and pads have a negative impact on the environment. Between production, consumption, and disposal of these items, they're not the easiest or friendliest on Mother Nature. So, if you're all about living a cleaner and more environmentally-friendly life, period panties are a natural fit. Washable and reusable, quality period underwear is long-lasting and can be used over an extended period of time. On average, and if cared for properly, period panties can last anywhere from 6 months to 2 years


Ladies, the pink tax is real. Aunt Flo is one expensive monthly visitor. Per the Huffington Post, the average woman will spend upwards of $18,000 throughout her lifetime on menstrual products, birth control, and other items to manage the pain of her monthly cycle. Tampons alone equate to over $1,700 of that estimate, with new underwear ringing in around $2,300. So, if you're looking for ways to cut down on the cost of your period, eliminating non-reusable products and replacement pieces is a good place to start.

Period underwear offers women a great solution to cut down on costs. Sure, the average pair of period panties is around $30, but again, they're going to see you through around two dozen periods. So, while the initial investment will set you back, you'll definitely be saving money over time. 

Less Stress

One of the biggest concerns with any period is the fear of leakage on your clothes and on your sheets. Period underwear takes care of those issues, too. Without the need to change tampons or pads, you can go about your life knowing that your underwear is taking care of it for you. In fact, many of the best options on our list can absorb as much liquid as 3-5 tampons. Many are even available in different absorbency levels, so you can wear the panties that work best for your specific flow.

How Does Period Underwear Work?

Period underwear looks and feels like actual underwear, with one noticeable difference: an absorbent lining. While there are some design differences with every brand, all period panties are lined with special fabric that works to absorb liquid, prevent leakage, and eliminate unwanted odor. Washable and reusable, these menstrual products are easy to clean and wear again and again.

Many of the brands on our list offer a wide range of styles in different levels of absorbency. As you look through product lists, each style is noted with how much protection it offers, with some even designated as nighttime approved. Simply slip on, wear throughout the day or night, and rest easy knowing your trusty period panties will keep you feeling fresh and clean no matter the activity.

Are Period Panties A Replacement For Pads & Tampons?

Yes! Period underwear is designed to replace pads and tampons. However, if you're feeling uneasy or unsure about the effectiveness, you can absolutely wear them in addition to traditional menstrual products. For those who are feeling skeptical, we suggest buying a pair and testing them out on a lighter period day, without the use of other products, to get a feel for how they work.

That said, there are a number of lesser expensive options that are designed to supplement pads and tampons. We've made sure to note those options on our list.

How Do You Clean Period Underwear?

While each manufacturer provides cleaning instructions specific to their pieces, almost all period underwear can be washed in the washing machine. Some options are even dryer-friendly, but it's always best to defer to the instructions provided by each brand.
