Top 10 Period Underwear

THE DETAILS
Here they are: the internet's best period panties. One reason why Knix's Leakproof Bikini underwear are so beloved is that they're made from the brand's PermaStretch fabric (a soft, stretchy, quick-drying material). Beyond that, they can hold up to three tampon's worth of blood and won't bunch up or look bulky under your pants.

PROMISING REVIEW
"I like these panties for two reasons: 1) It feels like you have nothing on and there are no panty lines to be seen under your clothes, and 2) With the crotch protection from leaks, you can have confidence that no accident will embarrass you. I will be trying different styles of these panties with and without the crotch protection."

THE DETAILS
If you've been using period panties for some time now, you've likely heard of Thinx. A leader in the space, Thinx makes products for those who menstruate or experience incontinence. The Classic Hiphuggers are one of their most popular styles, having amassed thousands of perfect 5-star reviews.

MORE TO KNOW
These period panties are highly absorbent, which is why they're recommended for moderate and heavy flow days. Also, Thinx frequently releases their Classic Hiphuggers in seasonal colors and materials, so if you love these, check back regularly to see what's new.

THE DETAILS
Simple and sleek, Proof's Leak Proof Light Absorbency Thong probably looks a lot like the rest of your unmentionables. Even so, these underwear are shockingly functional, with a multilayer Leak-Loc™ system that pulls in moisture and protects from spotting and an invisible leak-resistant lining.

MORE TO KNOW
Because this thong only holds one tampon's worth of liquid, it's best used on light flow days.

THE DETAILS
We'll start with this: One reviewer claimed that these panties made it feel like she wasn't even on her period. That's cause enough to hit "add to cart," but if you need more, they're also made with ModiBodi's award-winning, patented Modifier Technology that absorbs blood, urine, sweat, and other bodily fluids.

PROMISING REVIEW
"I always used pads and could not get into the idea of using a menstrual cup as I never even used tampons. I was getting very tired of pads, not even from the cost but because of the guilt towards the environment. I did a bit of research and went for ModiDodi as I found them to be the more attractive looking period undies. I have to say I’m just completely blown away by the comfort of these lovely underwear, how much they hold and how they don’t even smell!"

THE DETAILS
Saalt is a leading name in the world of non-traditional menstruation management methods, so it's no surprise to see their Leak Proof Thong made the list. If you're averse to panty lines, this mid-rise, lightly-absorbent thong is definitely the style for you—and guess what? There are four delightful colors to choose from.

This particular pair of period panties is best for light flow days or as a second line of defense against leaks.

THE DETAILS
Cheeky with a high leg line, it's extremely difficult to tell these are period panties at first glance. However, they're designed with a built-in absorbent pad that can handle your cycle and incontinence too.

We love to see size inclusivity, and we're happy to share that TomboyX made their First Line Period Bikini available in sizes from 3XS to 6XL.

THE DETAILS
In addition to having an impressive 10,000+ 5-star reviews, these are the fourth best-selling product on Amazon in the category of hipster panties. That said, it's worth mentioning that INNERSY suggests pairing these period panties with other menstrual products for a truly leakproof cycle. 

PROMISING REVIEW
"I honestly was a little skeptical when buying these. I thought there was no way they were going to be able to handle my flow for a whole day. These panties definitely proved me wrong. They absorbed more blood than any other pad ever has. On top of that, they are comfortable and didn’t bleed through during my time of the month. I definitely will be buying more."

THE DETAILS
Got a heavy flow? The High Waisted Period Panties from Period Co have you covered. With two absorbent layers and an additional leakproof one for good measure, these underwear are also a reliable option for those dealing with postpartum or perimenopause.

CARE TIP
Before throwing these in the washing machine, give them a good rinse and wring them dry.  

THE DETAILS
With a lace-trimmed, high-rise fit, these period panties are delightfully feminine and fun. They're made with three layers of breathable fabric and can hold up to three teaspoons of blood.

MORE TO KNOW
Who says periods can't be cute? These underwear come in six different colors, from Intense Green to Ruby Red. Not to mention, they're stain-resistant—so go ahead and get the beige.

THE DETAILS
Aisle's Boost Boxer Briefs have enough absorbency to hold eight tampons' worth of liquid. And as if that's not enough good news, these briefs come in sizes from XS to 5XL.

PROMISING REVIEW
"My go-to is a menstrual cup, but I experience very heavy flows that lead to constant leaks. Pads were uncomfortable and something always had to go wrong. I never had a cycle where I didn't bleed on something. But the very first time I tried out the Boost Boxers and I've never been so impressed in my life. They're comfortable and have great coverage leaving me confident that I'll never have to deal with a mess, no more running to the bathroom in an emergency. Just throw these on during heavy days or even days where there's no real need for a cup and I'm still secure and good to go."
