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.

    The whole experience of having a period sucks, but this makes it drastically easier at night alone. Sensory friendly, no pinching in weird areas, and wide hips accommodating. The area it covers is very wide and covers up through the lower back. I don't want to jinx myself, but it's been completely leak proof so far on the worst days.

    Obsessed

    As someone with an extremely heavy flow, I can vouch that these actually work. Wore them from 7 pm to 9 am the next morning with no leaking whatsoever on the first day of my period. Was shocked at how dry the underwear feel even though you’re bleeding into them. *****% recommend buying a pair.

    Great overnight wear

    I wore this on a pretty heavy flow night and slept great with no worries! Put the pair on around 9pm and finally took off around 5am when I could tell it was pretty full.

    Very Absorbent

    I really was happily surprised that, as a heavy bleeder, these actually help up all night long even on my heaviest nights. No changing in the middle of the night is really a nice surprise!
