What Is Period Underwear?

Being a woman is great in so many ways, but one of the perils is dealing with your menstrual cycle (the cramps, the bloating, and, most of all, the blood). There is so much blood every single month. Getting period blood out of your underwear is also very difficult. In this article, we're going to examine how period panties work and how well they work.

Are Menstrual Products the Best Choice?

Traditionally, tampons and pads are the go-to solution for dealing with blood. Companies that make sanitary products for women are a $15 billion industry. Women are spending several thousand dollars on sanitary products over their lifetime, and these products are full of chemical-based products (bleached rayon, cotton, and plastics) that have no business being anywhere near our bodies.

Besides the physical risk of using pad and tampons, there's the green factor: Are pads and tampons good for the environment? Most of these products end up in our landfills, but women have accepted this fate for years because there weren't other alternatives (with the exception of menstrual cups).

The Science Behind Period Underwear

The concept of menstrual underwear has been around for a long time, even before my time (I was born in the '70s). We're finally getting to a place where we can talk about our periods and advertisers can tackle menstrual issues as well without being called crude. There are essentially 2 types of period panties:

  • one type holds your pad in place
  • the other type replaces a pad/tampon

Panties That Hold Your Pad in Place

PantyProp panties offer undies that hold the pad in place. This addresses the issue of the shifting pad, which is often the cause of leaks. The idea of PantyProp is very straightforward: There's a slot for the pad to slip into. There are 2 styles to choose from: a bikini and a hipster.

Brands such as Hesta, Harebrained Designs and Bamboo Viscose all offer a similar style of panty: a comfortable, not too bulky underwear with a gusset panel. The panel prevents leakage, but you still need to wear a pad/tampon with these panties.

Panties That Replace Pads/Tampons

The outside layer on Dear Kate is made of a combination of nylon and lycra, and topped off with a liquid repellent finish. Thinx undies uses a multilayer system including a "moisture-impermeable polymer layer," a "moisture-absorbent layer," and a "moisture-wicking layer."

The main thing about Thinx panties is that the material is comfortable, thin and attractive. Unlike the diaper-like material on pads, the material is breathable and natural feeling. Thinx offers a variety of styles: hip hugger, high waist, boy short, sport, cheeky and even a thong. Padkix is very similar quality and technology to Dear Kate and Thinx.

Comparison of All Panty Types


PantyProp is "a patent-pending technology and specially designed gusset for underwear, swimwear, leggings and bodysuits that provide leak-proof protection for women, girls and men. The built-in absorbent gusset is perfectly angled to collect your flow immediately, ensuring stain-free comfort. It can be worn with your cup, tampon or a pad. Sanitary pads are locked in and securely held in place in the dri-tech mesh gusset." The panties range from $17-$22.99 a pair.

  1. Before your first wear, give your PantyProp style a quick stretch.
  2. If using a pad, remove the adhesive release paper and press pad firmly into the PantyProp gusset, like you would in your normal underwear. Pull the dri-tech mesh around the edges of the pad. Smooth with your hand until pad is flat.
  3. Pull PantyProp style up snugly to your body.
  4. For proper protection, change your pad, tampon or menstrual cup with regular frequency.

Backup Layer of Protection

Harebrained period panties feature a double-lined black gusset panel. These undies don't replace pads or tampons, but they offer an added layer of protection in case of pad or tampon leakage. These panties are sold for $8-$12 a pair.

Pad/Tampon Replacers

Padkix period panties are composed of multiple layers: Polyester outer layer, cotton inner layer, and a combination of bamboo microfiber and cotton for absorbing. This company started out as a kickstarter project and they have successfully launched a website due to their popularity and great reviews. The price tag ($25) is slightly cheaper than Thinx and Dear Kate ($32-$39 and $24 for the thong)

There are so many different styles of panties from basic, to sporty to fancy. Dear Kate undies might be on the pricy side, but they are built to last and you get a 1 year warranty.

How to Get Blood out of Panties

If you are a woman, chances are you've dealt with trying to get blood stains out of your panties/sheets/couch. Now give yourself a pat on the back because not only is life busy and and complicated, we have to deal with blood stains on top of everything else. I'm going to offer a few tips and tricks to getting blood out of panties.

How to get Blood out of Underwear From a Period

  1. Use cold water to soak your garment. You can add soap to the water or even 1/4 cup of hydrogen peroxide. The main thing is that the water is cold (hot or warm water will set the stain)
  2. Scrub the stain, rinse and repeat until the stain is out.
  3. You can use the washing machine, just make sure you use cold water and use a stain removing product on the garment.
  4. If you need to wash/scrub multiple times, make sure to air dry the garment. Using the dryer will set the stain if the stain is still there.

Period Panties: The Way of the Future

If you've read this far, I hope your brain isn't overflowing with information; rather, I hope you feel more confident in choosing the type of period panties that's right for you. You can spend as little as $7 a pair and as much as $38 a pair, but every period panty company differs in technology, quality and style.

In the case of the lower priced period panties, the problem is that over time the protective layer will separate from the underwear and you'll have to replace them. Might be a case of you get what you pay for. As for the pricier period panties, many of the companies that charge a higher price stand behind the quality of their product, and some offer exchanges and warranties.

Either way, you have to decide what's right for you. In any case, period panties are a god-send to women everywhere!
