The Best Period Underwear Is…

The list below shows you the best period panties you can wear in 2021.

The list is structured to cover the best period underwear in different categories.

Without further ado…

  • Washes well even at low temperature.
  • It does not shrink.
  • Expensive pad underwear, compared to similar products.

Thinx is, arguably, the best period underwear brand on this list.

Thinx is so popular for two good reasons:

a) All Thinx undies we’ve tried took our 21 point tests with flying colors.

b) All of our testers loved their products.

For example, one woman said she was sure there are no stylish, comfortable, and functional period panties.

And then, she tried a pair of Thinx.

There’s no surprise that Thinx period panties scored the highest in our tests.

Yet, compared to a maxi pad, it takes them just a bit longer to absorb liquids.

Lunapads’ underwear is a bit different than the other period panties on this list.

The brand has created removable inserts that absorb your period (along with an absorbent liner).

Without the entire protection built-in, the insertable part feels like using a reusable pad inside your underwear.

Not all of our testers liked the concept.

Yet, we have found that these period panties absorbed even faster from all tested products than Thinx!

Until now; this pair of Knix undies changes all that.

Not only super absorbent, but the Leakproof Thong by Knix has a fabric that dries two to three times faster than regular cotton.

Cheap and effective, these panties are made with a built-in pad that absorbs up to three times the amount a regular pad.

You can wear them as a normal pair of underwear, or mix them with other disposable products if needed.

Moreover, as they’re fully recyclable, you can just toss them away without regrets of destroying the environment even further.


What Are Period Panties?

Period panties look and feel like regular underwear, with one big difference.

They are designed for that time of the month, with protective layers of fabric that prevent blood from leaking through.

Also, compared to disposables, period panties are much more economic and sustainable.

Most pads and regular tampons (we go through tens of thousands in a lifetime) end up in landfills or down the toilet, with serious consequences for the environment.

Is Period Underwear Safe?

Those of you used to pads, tampons, and menstrual cups might shake heads at the idea of wearing menstrual underwear.

But, trust me, investing in a pair will save your mental sanity and bedsheets.

Period panties are sanitary and are designed with anti-microbial and moisture-wicking properties to prevent odors.

However, to stay safe it is critical to choose the right period panty, based on your needs and how heavy your menstrual flow is.

If you’re nervous about using menstrual underwear for the first time, I recommend trying them on first.




Start by using them as extra protection against leaks on your light days.

You can also pair them with other disposable products, such as tampons or menstrual cups.

How Does Period Underwear Work?

Some menstrual panties are designed to be worn only as backups to a tampon or menstrual cup.

Others are built with multiple layers for more difficult periods and extra protection.

For example, Thinx underwear (a popular period panty label) has four different layers of protection:

  • moisture-wicking cotton
  • odor-trapping lining
  • super-absorbent fabric
  • leak-resistant barrier

Can I Wear Period Undies All Day?

Yes, if you follow the correct cleaning routine.

To keep your period undies clean, you must rinse them first under cold water.

Only after, you can put them in the washing machine.

You have to make sure you clean your period underwear properly as leftover blood can lead to bacterial growth.

Once properly cleaned, you can use them all day, feeling safe, secure, and sustainable.

Benefits of Using Period Panties

Most of them are reusable so you’re saving money and the environment at the same time.

Period panties are the most cost-effective choice if you want to cut back on waste.

However, to enjoy the benefits it is critical to find the most suitable period panty for you.

Chances are you will experience a leak or mishap even if you’re wearing tampons or pads.

Period undies can help, either as a backup or at the end of your period.

Moreover, it is much more comfortable to wear them than tampons or menstrual cups.

Now it’s your turn…
