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.

    Soft, comfy, and absorbent. I did have some leakage during a heavy flow overnight, I’m between a small and a medium which may have had something to do with the leaking. The absorbent material is nice, at no point did I feel like I was sitting in a puddle and the machine wash option is a win-win.

    Not Exactly What I Expected

    I will admit that I was skimming quickly as I was filling my cart because I was buying during a sale and didn't want any of my items to sell out, but I just assumed something designated for sleep would be full coverage. These are not, and so after wearing them overnight once and only realizing my (messy) mistake in the morning, I don't use them anymore. I should have bought more full-coverage briefs, instead.

    Change in design leaves much to be desired

    I have several pair of the older style of boxers with an elastic band that fit well (albeit run 2 sizes small) however I ordered some replacements and the waist band is now just folded over spandex material and does not have the elastic to grip which means all night long I fight to keep my boxers up when I flip flop in bed.

    Perfect for active sleepers

    My daughter is a very active sleeper, tossing and turning during her sleep, and NO pad would ever do. But this works! No leaks and no "side leaks".
