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.

    Does the job well

    I suspect my flow is a little lighter than other people and I found that I don’t really need the extra protection that these underwear provide. They’re a little bulky to me compared to what I usually wear (bikinis). However that being said they do their job well and I have had no issues with leaks when sleeping.

    Comfy and okay heavy flow coverage

    I wore these last night and it lasted for 5 hours on a heavy flow. I’m sure it would’ve lasted overnight but when I went to pee, my blood was on the side of my thighs right next to the crotch area. Sorry TMI.

    I think because boy shorts are hard for things not to leek in the side because of how they are constructed. So if your flow is heavy, your legs are going to squeeze the moisture out onto the sides. So I feel like if the sides had some wing coverage, this would be 5 stars. I do feel like period company’s Extra coverage high waisted in organic cotton gets 5 stars

    Runs big.

    I bought an XL based on the size chart. I am a true size 12. They run pretty big so I'd recommend sizing down.

    Pink shorts run big!!

    I’ve been a customer for years and absolutely love this product, but the pink shorts are so huge on me. I’ve always fit well in the black large but this pink ones in large swallow me up. Just be cautious of this when ordering, hopefully this will be changed soon.
