1 pair absorbs 9 tampons of flow

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

Absorbs up to 9 tampons worth 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.

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.

    Underestimated the flow

    These are so comfortable! Unfortunately for me I over estimated my flow :( I typically go through an ultra every 1-2 hrs on my first day. I wore these shorts as my only protection for the first day and bled threw after 4hrs. I think these would be great for 2nd or 3rd day or pairing them with a tampon. I will be giving these another shot as they are incredibly comfortable!!

    Finally!

    We've finally found a solution for heavy cycle overnights! I bought one pair for my daughter to try and she loved them so much she washed them everyday so she could wear them again the next night. They seem to wash and dry well, are really nice looking and she says they're super comfortable. Thank you from one relieved mama!

    Works!

    (I use a night pad on top of this) Had a nighttime leak for the first time since using these underwear and I was really impressed! A leak that missed the primary pad lining of the shorts that would have usually ended in a big spot on my sheets didn't make a dent in these. Stained the shorts, but not my sheets.

    BIG warning- these undies absolutely run large. I am usually a size S and these were huge on me- I had to wear bike shorts on top initially so that they'd actually stay in place. Since then I've been gradually shrinking them in the wash which I guess is working. Order a size down if you usually wear a small.

    Huge, and I mean that in the best way. I’m a restless sleeper and even though regular period panties can hold my flow overnight, I move around so much that I usually end up staining the sheets. Not with these! The gusset is bigger than the pads the hospital gives postpartum, and I mean that in the best way.
