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.

    Can’t believe I’ve menstruated since I was 13 without these!

    Not to be dramatic or anything, but how have I had a period everyday without these?! I wish I had these my whole life! I’m usually a bikini underwear girl, but I still feel like I’m going to leak like I’m not getting full coverage. These are so comfortable I can wear them as my underwear AND shorts for the first days of my period and overnight. I usually have to sleep with my period in mind in the first days and leak on my pants 🤦‍♀️ but these are AMAZING!! Well worth the money. I wish I had started with the sleeper panty last year.

    I started using a no named brand of period underwear for postpartum years ago and thought they were top notch. I had no idea!! I will absolutely use these for postpartum baby number two!!

    Size down

    I normally wear a size 2x in bottoms, but I got both 1x and 2x of these shorts and the ***** better. They fit snug but NOT tight, and so I feel way more secure in wearing them overnight or on particularly heavy days. The 2x is just loose enough that I had to keep adjusting them/pulling them up even when I was lying in bed. I would still use them if my body shape changes in the future,

    Great for lounging and sleep

    I love the way these fit my tummy and legs. So comfy and I've got some curves. Great flow protection too.

    So comfortable!

    I have very heavy periods and I wore them overnight on my heaviest night. After 6 hrs I had to go to the bathroom and decided to change them, but they probably could have lasted all night I I hadn't gotten up. They look like bike shorts, so I put an oversized tshirt on and walked the dog in them.
