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.

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.

    Great absorbency for most, but needs more petite sizing

    My partner and I switched from Thinx to Period., and we both think these sleep shorts are so much more absorbent and better designed, especially for those with heavier flows. My partner has an extremely heavy flow, and they swear by these. However, I'm bummed that this product doesn't offer an XXS or Teen sizing for us petite girls… The XS is not snug whatsoever on me, and I carry most of my weight in the thighs and hips! For reference, I'm 5'/152cm, 105 lbs/46 kg, 24" waist and 34" hips, so I thought the XS would be alright. I'm really glad there's such a wide size range for larger sizes. I would love an XXS though! :')

    Tears easy

    Got a replacement pair after my first ones tore without a reason. Always wash per instructions. Never caught on anything. The replacement pair is barely 5 months old & have torn as well. Will not be purchasing anymore as these are expensive and I rather not waste money.

    Love these so much! NO LEAKS

    They were comfy and oddly more breathable than I expected which is great for me. Felt comfy and amazing to sleep in. Did stretch out over time and got larger though
