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. If you want a more relaxed fit, we recommend sizing up!

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.

    Very comfy but don’t hold shape

    These are super comfy but the cotton stretches out and stays stretched. The absorption part is also super bulky and diaper like, I wish there was a lighter version the pad part in the front bunches up and is just very bulky. The seams are also unraveling after 2 washes which is disappointing. Overall they are comfy but will not buy again.

    These work great!

    I am very happy with these sleeper underwear. At first I thought they looked like they were a bit oversized, but I found they are great for sleeping. I wore them on the first couple nights of my period when my flow is the heaviest. I had no leaks and no discomfort, and I wore them on their own without any pajama pants. It was very comfortable and worry-free. I plan to buy a couple more because I liked them for night time so much.

    I really want to love these…

    I really wanted to love these sleeper shorts. I had a different pair from another brand that I absolutely loved! So I guess I had high expectations - they fit very weird like the lining is off. So it makes them uncomfortable and with that I can’t wear them alone. Unfortunately, they will just have to be extra that go over another pair of undies for back up while sleeping.
