Get comfortable leakproof period protection with this ultra absorbent high-waist period panty, a breathable period brief made from bamboo and a light absorbency thong that feels just like regular underwear.

Many people have been making the sustainable and economic switch from single-use period products to reusable menstrual items . Among these popular alternatives: period underwear

If you’ve never tried period underwear before, the idea of simply free-bleeding into an undergarment may seem counterintuitive and possibly terrifying. How is a thin piece of fabric supposed to absorb everything, keep you feeling dry and comfortable and also preventing odor? 

The inner workings of most, if not all period panties, are fairly simple. According to many brands , the stain-proof gusset section is typically enforced with multiple layers of a unique technical fabric that absorbs and holds liquid, while the top layer is constructed of moisture-wicking filaments to make the underwear feel instantly dry and eliminate any unpleasant smell, all while feeling and moving just like regular underwear. 

If you’re now imagining a swirling sea of red come laundry time, it turns out period underwear care is pretty low maintenance and much more sanitary than you would think. Many reviewers and underwear care guides  recommend giving the panties a quick rinse before tossing them in the washing machine with cold water and mild laundry detergent, then leaving them to air dry.  

It’s important to note that period underwear companies offer a range of absorbency levels in their panties and briefs, so you should find an option that meets your anatomy and flow needs. 

In the list below, you can find period underwear in a variety of styles, absorbency levels and price points that can be great for anything from backup leak insurance to first-in-line period protection. Plus, find out what others had to say about their own experiences with period underwear.

A highly rated period panty made with bamboo rayon
This affordable pair of period underwear by Bambody has over 10,700 five-star ratings and is made using ultra-soft and breathable bamboo fabric. The naturally cooling properties of bamboo rayon help to wick away moisture quickly while the wide, full-coverage gusset offers absorption protection from the entire front to back and can absorb up to two tampons' worth of liquid. The company recommends ordering a size up.

Promising review: I bought these almost a month ago and I can't say enough good things about these panties! They actually work. They hold a lot of liquid and somehow wick it away so you don't feel wet or humid. And the best part is NO tampons! I tried these out on a heavy period day, and it worked overnight and into the next morning! I would feel a gush and go check my clothes, but there were no leaks! Amazon customer

A pair of high-waisted and ultra-absorbent underwear
For greater protection on heavier days, these high-waisted, full coverage underwear by Thinx are a good option. The four-way stretch mesh sides allow for a comfortable wear and the panties can absorb up to four tampons' worth of liquid.

Promising Thinx review: Love these and wear them while sleeping. Like that they are high waisted and fit snugly without being tight or constricting on my stomach. They come up super high on me, a couple of inches above my belly button but I like that. So so comfy and no leaks! Basically dont feel anything while wearing them. Such a great alternative to tampons. Natashya J .

An affordable three-pack of 100% cotton-lined period panties with a full coverage fit
The extended gusset on this affordable period underwear is lined with an absorbent waterproof layer that is topped with a layer of 100% cotton. These high-rise panties are lightly absorbent, making them a good option for back up protection or lighter flow days.

Promising review: I wore a pair last night because I was supposed to have already started my cycle. I woke up this morning and I felt dry so I figured I didnt start but when I used the restroom to my surprise they were full of blood which shocked me because I felt absolutely no moisture. I have a rather heavy flow for the first three days of my cycle so for these to not only keep me feeling dry when theyre full of blood but to also not even leak through onto my clothes or my bedding well they get a full five stars from me. There was no gross smell from blood just sitting in them. Monique Proulx Masters

(This style is also available in super and heavy absorbencies.) They feature a lower-rise fit and a comfort-stretch band.

Promising Thinx review: I've tried a number of brands of period underwear, but this specific style of Thinx is the absolute best. Unlike all of the other brands out there, these actually have enough coverage in the back. They're also super soft, breathable, and comfy. And, they're super cute, especially the pink ones! I wear these on light to moderate flow days. Marilee

Promising Thinx review: Im almost 40 and so sad Ive had a period for 25+ years and only now have found these! Im also a nurse so having these as a back up for work and when sleeping is the best. I have 4 pairs and love them so much! Theyre also comfortable and not hideous. Kelly M.
