Skeptical at first, but...
I'd heard of period panties before, but I was really skeptical of their performance, and also how they would feel and look on. I was pleasantly surprised with Knix! The boyshort style is so cute on, and the lining isn't diaper thick like I'd assumed. They're also seamless and don't show much under clothing. Knix has other styles, too, like a thong, that'd I'd be willing to try. I like to wear these when I sleep as "backup." They're so comfortable! I'm really grateful to my friend who recommended these. I haven't tried wearing them on their own, yet. To be honest, I am still a little skeptical of their ability to protect from leaks, etc., especially with how heavy my flow can be sometimes. For now, I just really appreciate the quality and comfort, and I feel protected wearing them as backup during the day or at night.

Great product
Can run a bit large. I like them to fit snug.

Awesome. Skin-like feel. Feel super absorbent.
Love these! Soft, comfortable, but stretchy enough that they conform to you don't sag or slide. I also love that they're thin and have that 'skin; feel, so I can wear them under dresses and skirts w/o worrying that it looks like I'm wearing a diaper. I've actually transitioned to these as my everyday panty because they're so comfortable and fit so nice. Def. a good purchase. Are they expensive? Yes. That's why I removed one star.... but otherwise, they're great!

Soft, breathable, & very comfortable stretchy material
Very comfortable, stretching yet strong material. Have not worn them more than trying them on, but I am hopeful I finally found a pair of period underwear that are effective and comfortable. I am post-menopausal, but use an estrogen suppository 2-3 nights a week and I have been looking for something that is breathable, comfortable, stretchy and non-binding. It doesn’t cut into your groin at the seams.

Highly recommend!
These are the absolute best. Used them after having a baby and they’ve been my go-to now every month.

PLUS SIZE BEWARE
The garment itself fits but IT IS NOT MADE FOR A PLUS SIZE BODY. The part that is supposed to "collect" barely covers one lip!! And it is not positioned right - why is half of my front slit totally open to bleed all over my clothes while half of my butt Crack is covered????? This is not acceptable!!!!!

Boo-Not what I expected
Disappointed. They are leaky with an odd fit in the most important places. I’ve had better luck with less expensive brands. It’s a bummer because I was excited about the thinner material.

I was super surprised at how comfortable these were. I'm usually a tampon girly so pads are something foreign to me, but I bought these to wear at night for comfort. They did not disappoint. They weren't to bulky and they fit snug but not tight to my body. No leaks at all ( I have medium to light flow) highly recommended you own at least one pair of these. I just bought a second pair. Thanks

She loves these form fitting and comfy period undies. Wishes they had been around longer.

Déjà je reçois l'item et l'emballage a déjà été ouvert. Je suis désolée mais ce n'est pas hygénique du tout. J'ai demandé un remboursement! Je m'attendais a un produit neuf et scellé! La culotte avait été remis non plié dedans ça paraissait! Bref, j'en profite pour l'essayer, elle taille bien son 3xl mais je suis déçue de la grandeur de la partie absorbante on dirait la longueur d'un minuscule protège dessous. Si vous êtes comme moi grande de fourche et que vous coulez vers le devant ou beaucoup vers l'arrière vous aller détester car assurément on va déborder. Je suis très déçue. C'est la première culotte menstruelle que j'essaie je ne sais pas si elle sont toutes faites comme ça mais c'est décevant. Je cherche un solution lavable durable et fidèle à mes besoins: partie absorbante plus longue au devant et un minimum en arrière et suffisamment absorbante la nuit. Je ne m'aurais pas senti safe du tout la nuit!

Great period panties! They fit well and are comfortable for night use.

These are pretty good. Way more breathable than other brands I've tried and so far have kept me protected from leaks. However, I wish I hadn't sized up after reading other reviews. I'm usually in between small and medium. I went for small, but even that was a bit loose. The fabric is pretty stretchy and gets looser after a few washes. I did get another one in xs and I'm very happy with those
