1 pair absorbs 9 tampons of flow

Super absorbent, sleek style made for heavy days. 

Absorbs up to 9 tampons worth of flow!

Yup. I’m for those days when your period has your foot down on the flow pedal. I have a little less fabric than the high-waisted, but with the same four-layer towel system I have just as much absorbency. My padding is designed to take whatever the flow throws, while making you feel extra secure and safe. Oh, did I also mention how cozy and comfy I am? Anything a tampon or pad can do, I can do so much better. 

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

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

You can see our size chart 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 an Octopus: Hi. I wanted to send you a personal message of gratitude for being conscious enough to stop using disposable products. Imagine me now, shaking your hand eight times. That’s what I’m doing. And sending you good energy with my two hearts. Tampons and pads take generations to biodegrade, cause endless pollution and they are frankly stupid inventions - and I should know what stupid is because I have eight brains. Be proud of yourself - you’re making a big change.

    Absolutely Love! 5 Stars!

    There is literally no other period underwear that I want to wear now because these are just that good. I’m about to order some more of the thongs and boy shorts. I think the run larger to compensate for boating and such so if you don’t bloat much size down!

    Nice fit and feel

    I HAVE NOT USED THEM YET. But I really enjoy the fit. They don't ride down and are higher waisted than I imagined.

    Comfy

    I love these, they worked better than expected. The only negative was my fault. I went up two sizes from my usual underwear size in this style and well they’re way too big now. My previous The Period Company purchase (in a less stretchy style at least 2-3 years ago) were too small in 2x so that’s on me that I couldn’t convince myself to stick with a 2x this time.
