Good For Pee
Period underwear is also excellent for any bladder leaking and can absorb pee. 
For those sneezes, laughs, and work-outs that often come with something extra, we’ve got you!
For that post-baby bladder, we’ve got you! 
For that post-menopausal bladder, we’ve got you!
And if it seems strange to think of an underwear company called Period helping out with pee, then remember it like this…
The end of uncomfortable, unstylish, undignifying incontinence underwear. Period. 

The greatest period experience that you and the earth will ever have. Period.

1. Put your Period underwear on.
2. Go about your day.
3. Sometimes you might have a leaky feeling- remember, this isn't you leaking. This is you flowing.
4. Whenever you go to the bathroom, do a little toilet paper 'tap tap' to absorb any excess blood.
5. Come home, change into a new pair of Period underwear to last the night.
6. Rinse your daytime underwear in water and put it in the laundry bin. You'll see some blood, but it's okay - it's your blood.
7. Go to sleep, wake up, repeat.

Our patent-pending four layer absorbency soaks up a full day of period blood. Our unique seam technology prevents leakage through the seams, and our top wicking layer keeps you dry.

Wear us instead of tampons and pads. 

Or, wear us as a back up until you feel comfortable. 
(although we won’t be second place for long!)

I have struggled with period management for years and I have tried everything, except period panties. They were expensive and I just couldn't bring myself to spend the money, but these... I was totally blown away. I have a very heavy period and they took it like it was nothing. Period. has changed the way I bleed. I cannot say enough about these panties. THANK YOU. Period. really has changed my life!

Finally, period underwear I can afford. It makes my life easier and it’s better for the planet.
Highly recommend!

Okay, I will have to admit to you I didn’t buy them for my period, but I did buy them for my bladder leak. Absolutely love them, going to be buying 5 more. I hate using pads and environmentally they are terrible! You do know there is a market out there for people like me.

I'm 48 years old and don't think that I've ever been excited to get my period (relieved maybe, but never excited). I couldn't wait to try my new period panties this month. They totally live up to the hype! Comfortable fit, no leakage even on my heaviest days, and no waste. Thank you for developing this liberating product!

My expectation was to put these underwear on while I was on my period, and live my life. And that's exactly what happened. No worrying about having enough pads or tampons, no going to the bathroom constantly (even on my heaviest days), and not wondering if I had to wash the sheets in the morning. For the first time in my life since I got my period, I spent the week just living my life. The end. Thank you Period Company.

During my last period, I bought 3 pairs of Period. undies from y’all. This morning, I started my first period since receiving those undies. Today has been shockingly surprising. Not that I didn’t have faith in your product, it’s still just mind blowing to experience it first hand. If I didn’t have cramps happening, I wouldn’t even know I was flowing. I’m dry, there’s no wet feeling at all, and it feels like I’m just hanging out in my normal underwear. I’m planning to send a follow up email after this period is over, but day 1 has been a 10/10 success. Thank you for your product, thank you for your time, and thank you for helping me flow the way nature intended.

I was so excited to try these! They're exactly what I was looking for in period underwear. Soft fabric, moisture wicking, they don't dig in at the legs, and exactly zero leaks! Yes, the padding exists and is occasionally noticeable. But like another reviewer said, it's a similar experience to wearing pads. Tampon users may have an adjustment to how it feels? But basically, I love them. I have the high waisted and the bikini and have the boy shorts on the way! Periods don't suck anymore, thank you Period!

Jeny - December 2020

These were the best thing for my 12 year old with Down syndrome for so many reasons!
She hates the sticky feeling of pads- soft Period underwear took care of that.
She has trouble coordinating putting pads into regular underwear and disposing of them appropriately- just changing out Period underwear took care of that.
She cries every time she sees blood- the black Period. pads took care of that.
Pads make her feel like she can’t bend, or sit, or run-she took her usual gymnastics class wearing Period.
I could go on... Thank you for an awesome product for my special girl- and for my peace of mind!
