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.

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.

    Worth but sore

    I love these. I wear them for every period I have. Mostly at night but sometimes during the day. However I’ve noticed that after a few hours I am super itchy and raw on my lips so I know it’s time to change it.

    Sensory Issue

    Ok, I am really struggling with the inside seam securing the padded section in place. It just constantly feels like it's rubbing against my butt as I move and it's driving me nuts. Idk if it's just where it's situated or what, but it's just making me hyperaware of my underwear in a way that I don't want to be. Otherwise, the underwear functions as it's supposed to.

    Great!

    Comfortable. Trustworthy. Worth every penny. Even the time waiting for my size to be restocked again was worth it. Keep up the good work you guys!

    Not true to size

    These were not true to size, so they bunch in the crotch and have gaps at my thighs. For what I bought them for (pregnancy) they are actually very comfortable on my belly and do the job but I would not wear them with a heavy flow afterwards as they don't stay in place. My pants size was an 18 - 235lbs pre pregnancy.
