Super absorbent. Built for heavy days. 

Absorbs 9 tampons worth of flow or five pads. 

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.

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 10 tablespoons, or 8-10 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.

    Good enough

    I wish the crotch was wider. The inside of my pants gets stained when it shifts. I teach preschool and am constantly getting up and down off the floor.

    Alternatively, would be great to get full coverage shorts (like the overnights) for lighter flows.

    love love love

    this product was exactly what i expected. it was comfortable for daytime and supportive through the night. i could have sized down for a more snug fit, but the fabric was breathable, and met my absorbency expectations. im thrilled about making the sustainable switch and minimizing my waste! i would definitely recommend.

    The best period underwear I’ve tried! Soft, doesn’t feel like sitting on plastic, breathable. Plus they absorb so much and I haven’t had any leaks. They’ve held up well to washing too.

    Best period undies

    I sized up and it's a little big but not overly so. Better than having it dig in when everything already suuuuucks. But they're so comfy, and they do exactly what i need them to! Rinsing was easy, kinda surprised at how much blood they hold!
