1 pair absorbs 9 tampons of flow

Super absorbent. Built for heavy days. 

Absorbs up to 9 tampons worth of flow!

Hi! I’m super-super-super absorbent and designed to handle the heaviest days of a period. I’m made of soft, comfy organic cotton and have a four-layer padded towel absorbency that holds your flow. I have a wicking layer on top, so I can absorb the blood super fast with no wetness. You will feel padding, but frankly, on those heavy days, feeling secure, safe, and leak proof is a pretty great feeling, alongside being so comfy and cozy. Warning: after you use me once, you will look at tampons and disposable pads and pretend you don’t know them. Be cold. They deserve it. 

When to wear: on your heaviest days. Also great for postpartum and perimenopause.

This style runs true to size. Order your most standard size.

How to take care of your Period.

Rinse for a few seconds.

Either hand wash and hang dry, or add to the laundry pile.

Regular wash, no bleach.

Tumble dry low or hang dry.

Do not dry clean.

None, zero, nada, zilch. We are proud to be one of the few period underwear brands that do not use any toxins in our products because who wants chemicals near the most sensitive part of their body? Not us. Or you.

Each pair of Period. underwear can hold up to 9 tampons worth of blood.

Check out our absorbency test video here.

How long will one pair of Period. last?

Everybody periods differently so it’s tough to be exact. Our average time is about 8 hours on a heavier flow day. Though some customers need to change after 3 to 4 hours, and others can go up to 14 hours (lucky them!). As your period gets lighter, one pair can take you through the day and night (just like regular underwear). But again, everybody Periods differently, so you need to take one cycle to figure out exactly how often you need to change. Start with a conservative estimate on your heavy days, and check in on your Period underwear after 4 hours. If you still feel good, give it another hour. Keep going until you figure out your limit. Here at Period, we find we need between 3 to 4 pairs on the first two heavy days, including evenings. And if you leak, please forgive us! Just this once. (Remember how many tampons you have forgiven). Treat the ‘leak’ as a gift and note the hour of your leakage. That is the best indicator of your ‘flow threshold’ how long the underwear will last for you.

Message from a Coral Reef: Hi! Thank you for using non disposable products. It may feel like a small gesture - but it’s not. I’m sick of getting tampons and pads getting caught up in my beautiful branches and you’re helping to keep that trash out of my home. Just one pair of Period means that 5 pads/9 tampons are never used or thrown away. Thank you! Next time you swim by me, stop and say hi.

    ♡ not sure if i’d buy this style again but i might try another

    these are very thick and absorbent but my problem with these is that the actual absorbent part doesnt cover enough of the back personally. i had to put a panty liner horizontally in the back to sit or lay down 😭. other than this they’re very comfortable and i like the seams are very soft.

    if u are in between sizes id go for the smaller size to make sure there’s no leakage from the sides. they’re a bit stretchy and pretty true to size or bigger.

    not sure if I’d buy this style again but I might try another especially since these aren’t too expensive!

    Love!

    Love these so much! I am slowly working my way up to using period underwear for a full cycle, but I am already feeling so much better about my flow and the experience of "free bleeding" after using these. I love how they are high waisted and they are super comfortable. Today, I actually forgot I was on my period! They also rinse out easy and dry pretty quickly.

    Great period underwear

    I like these! I think that they have better odor control and absorption than my older underwear from Thinx. I also didn’t experience any leakage overnight, which is important because I move around a lot while asleep.

    Decent for the Price

    This is one of the less expensive options on the market, and comfort-wise, I've had no issues. It's also great that you can dry them in the dryer since air drying takes a long time and requires more pairs or switching to other products since I'm still trying out period underwear, and I tried a few different brands after doing some research online.

    One thing to note, I bleed fairly heavily on days 2 and 3, and I decided to wear this to my shift at work and not bring a backup pair since I'm still trying things out and don't have pairs to spare. This pair lasted about 5 hours, since about 5.5 hours after putting them on, I noticed the sides were starting to feel damp, and I could pat the underside on the outside and get blood out. So, it'll last, but not for a full workday on a heavy flow day.

    Also, I sized up from my regular underwear size based on the sizing chart, which is fine. Just be mindful.
