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.

    An "I'm Sorry" gift from Mother Nature

    I love these panties! I'm telling all my friends about them! My periods are awful and heavy; I experience major gushing, leaks, you name it. With these, I have extra backup, and I don't have to worry about messing up my clothes or worrying where I sit- no more putting sweaters or blankets on chairs! Thank you guys so much! I love you!

    They shipped fast and arrived fairly quickly. Only delayed a day, but that was due to USPS. Product is great quality and does exactly as advertised. I went from skeptic to believer with a single use and ordered more, gladly. 100% recommend for everyone.

    Comfortable without the fabric feeling bulky or crunchy or leaving lines in my skin, and no chafing.

    Very sturdy!

    I tried these in the cotton and the microfiber, and these ones feel very secure! There is less stretch/give in the material, but still very comfortable for day or night wear!

    Only Few Complaints!

    I really love these!!! I ordered a 3XL in hopes to have room to move around because I wasn’t sure how they would fit.. they’re perfect!

    I will say: I wore a pair for about 4 hours and I bled through the sides pretty badly. I’m a very very heavy bleeder for about a day or two. I now know I can’t wear them for more than 2 hours on those days; which is annoying to take your pants off to change your underwear!! But I think I may order some pads to help with those days.

    My only other complaint is that I wish it were a lighter color. Personally, I need to see how much blood is on the underwear to gauge how much longer I can go before changing them. I am inconsistent and need to visually see it. I understand there may be stains and that’s why it’s all black, but I don’t care about that!
