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.

    New material isn't as good

    I love these sleepers and recently bought 4 more pairs to wear during the day on my heavy days. Idk what it is, but the fabric of my new ones is different, and unfortunately they don't fit as snugly and almost feel like they hang down in the crotch. I can definitely tell the difference between my original 2 pairs and the 4 new ones I got. They still work great, but unfortunately, not quite as comfortable

    FREEDOM! Favorites to sleep in

    I love the freedom these give. You do have to shower right when you get up because you have a mess flowing freely throughout out the night. The blood will dry on your skin up the front and up the back of your a heavy bleeder. It’s still liberating.

    Comfy!

    I only used it for one night with a pad but had no leaks which was my goal. I have pcos which gives me a heavy unpredictable period needing all the sleep protection I can get. In the past that meant a towel but now I’ve been cycling through trying out different period underwear and products, glad I found this inexpensive option. I hope these last through a couple washes in the future. They were a bit heavy to wring out hand washing.

    I love these!

    I'm never going back to pads! I love The Period Company period underwear in general, but especially the sleeper ones. I've never bled through them even on my heaviest nights and they're so much more comfortable and convenient.

    Best period underwear for sleep

    I have very heavy flows, especially my first few days of my period, and these have been such a lifesaver. I no longer have to worry about leaking all over my sheets and I don't have to jump out of bed super early in the morning just to change my pad before a leak happens. I can finally sleep peacefully and sleep in knowing I'm fully covered. I also love that the waistband fully covers my stomach and doesn't have any elastic that digs in, and they fit true to size. Super comfy, super coverage, I'm in love!
