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.

    Teacher review

    Honestly, seeing the other reviews made me question buying these and also question if these are a hit or miss…I must’ve gotten a hit because I love these. As a teacher, running around with little time for a restroom break, overstimulation, and anxiety already maxes my daily energy. Add period cramps, nausea, and fatigue…and my cup runeth over. These underwear saved me both time and stress; truly relieving me of spillage (metaphorically and physically).

    I put these on last night (11pm) as I was noticing the start (and Xavier-LDS- gave me a heads up) and didn’t take them off until 8pm, as I had to help my cousin move directly after work. In all this I was comfortable and never leaked. I brought spare underwear and a pad just in case….but I never needed it. For reference, I usually go through four-ish heavy pads on my first day and I bought a size L.

    These kids were really trying me today too…but I was in high spirits and carefree thanks to these! They don’t take too long to wash either; I’ve used them three times now and they have been great.

    I will be getting more (purchased at Walmart).

    Leaks

    My 13 year old just started her periods, I bought her 5 pairs and she is leaking through them , even though her flow is not heavy. Disappointed as my 15 year old has been using period underwear for 4 years without issue

    Comfortable, not totally doing the job. Also quality, meh.

    I purchase these for my teenage daughter. She still wears cotton pads with them bc they don't always absorb well. They also tend to unravel where the elastic meets the cotton at the waistline. She does rave about how comfortable they are! She mostly wears them for comfort, but they are a help if she starts menstruating without otherwise being prepared for it. Quality is meh, seeing as how I replace them regularly due to the waist issue. Please fix this ongoing issue!

    Would buy again

    I did not last as long as I expected on my heaviest days but no mess was made. My only suggestion would be to extend coverage further up the back and front.
