1 pair absorbs 9 tampons of flow

Heavy absorbency: designed for heavy nights, mid flow nights and outrageous day 1s.  

Absorbs up to 10 tampons or 6 pads of flow. 

I’m dedicated to giving you a good night’s sleep on your period. I have a built in five layer padding that absorbs vertical flow and horizontal flow, because when you sleep your period can flow a little differently and I want to make sure your night is leak proof.  I’m made of soft organic cotton and am cozy, comfy and snug so you feel safe and secure and like you’re wearing a combo of your favorite leggings and PJs. I’m also great for those outrageous first heavy days, when if you have an option of laying on a couch all day, you take it. Sleep well.

When to wear: on heavy nights, or very heavy days.

This style fits like a true bike short. If you want a more relaxed fit, we recommend sizing up!

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 a used tampon: Hi, I’m a tampon that was last used in 1946 - only once - and I’m still languishing on a land fill. As you can imagine, I’ve had a lot of time to reflect. What was the point of me? Why did someone use me once for just a few hours and nearly a hundred years later, I’m still here? Why? This feels like a pretty stupid system to me. Please overthrow it! Please use non-disposable products so that no tampon ever has to feel this useless again. Thank you.

    Should have sized down

    Type 1 diabetic with an insulin pump. I was disappointed that there are no pockets to shove my pump in. However that only added to the problem I had with them. While they "fit" they don't stay up on their own, when I tried to clip my pump to the waist band that was only made worse. Seems to be enough stretch to them that I should have sized down for these. They were extremely comfortable to sleep in.

    Customer service is excellent and Best of all the products are well made and these sleepers are so comfortable. If you are someone who has a hard time with tampons and cups/discs these are much better than pads, especially for nights or days at home lounging around. I recommend this company to everyone!

    Love!!! So comfy and fit so well. It feels just like biker shorts and is such a comfy sleep. Way more comfy than wearing a pad to sleep. I’m so beyond happy.

    Black shorts vs Pink shorts are very different styles

    I really love these underwear. I use them every cycle. Ive had a couple of black pairs for over a year now, and I just ordered two of the berry colored ones. I felt it was important to share that the cut and style between the two are very different from one another-- the black ones are very high rise and nice and snug on my thighs. The berry ones are MAYBE mid rise, and are wide around my thighs... which isnt super ideal for heavy flow days. I still enjoy them, but hoping they will shrink up in the wash as they also feel much larger than my OGs as well. I ordered size XS in both. Im 5'2" 115lbs for reference. The black ones are almost too small. Hope this helps!
