Flowing Is Knowing

ABSOLUTE GAMECHANGER!
I was wanting to switch to something more sustainable for my periods, and menstrual cups seemed like they had a steep learning curve. As soon as I found out about Period Company and how much more affordable their period panties were in comparison to other brands, I thought they would be worth a shot, and they are! I sized up to a large, even though I normally wear a medium, and I'm glad I did. I did not want something tight pressing on me when I'm experiencing cramps, and these fit great. Nice and secure without being too tight. I definitely recommend sizing up. I can tell that I am wearing them under clothing, though, so that might be something to keep in mind. I often wear looser clothing on my period, so it's not really a problem for me. In terms of absorbency, my flow is only medium on my heaviest days, and I never felt like these were leaking. It took getting through two periods to really adjust to "flowing," but it's worth it. I think about dealing with my period less on heavier days, knowing that I have great protection. I have even been able to work out on my heaviest days. and work out on a mat without feeling like there would be a mess. Definitely recommend these to anyone who wants to switch things up for their period. When I'm cramping quite a bit, the thought of using a tampon is just not appealing, and now I know I don't ever have to go back to using them again. These are better for the environment, and better for my needs!

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.

This makes me feel so happy and validated. When I told me doctor that I think tampons and my menstrual cup we’re making my cramps worst she looked at me like I was crazy… I just added it to the list of “pelvic pain that may or may not be all in my head” and kept using tampons on heavy days. So just even the fact that there are other people who experience this is a big realization. Also - my period underwear is literally the perfect size to hold a hot water bottle in place of my asshole uterus. Ahh I just love this and what you’re doing so much. Thank you for doing the work!!

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!

No questions but I wanted you all to know that even a few days in to my first time using your underwear, I’m never going back to anything else! I only purchased 3 to try and I had to use a tampon today and within an hour I have cramps — which I haven’t had the past few days (I’ve been washing them daily and forgot to dry them last night to have a pair for today, hence the tampon). At first I was convinced I wasn’t going to like period underwear. But in less than a day I was a believer and didn’t even notice them anymore. Thank you for this product!

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.

A., October 2020

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!

Here’s my period story:

My daughter is 7 years old and I always would let her (and my son-they’re twins) see me change my pads and we talked about periods since they were young enough to ask me “What’s that?”. Now my daughter cannot wait to get her period underwear and my son is a little bummed he won’t get any! ha ha! she likes to watch me rinse in the shower and says that she will take good care of hers just like mine. So please, keep the good work up, I want to have her for hers when she starts her period.

thanks again,

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!)
