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!

You can see our size chart here.

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.

    So Comfortable, holds a lot!

    I love these! It is so comfortable and holds a lot. They fit well under my skinny jeans. I wore them as shorts under my skirt on both period days & non-period days. It can get icky if there is more lining being released, vs just blood; the lining gets in the way of absorption - I would just clean it off with some tissue paper.

    Because it can hold a lot, be sure to thoroughly wash it and dry it. I wash it by hand first, squeezing the gusset as much as possible with a soap, air dry for a few days. Then machine wash and air dry for a few days.

    Everything I wanted and more!

    These are excellent. They're honestly more protective than my flow needs but that's okay! I got one pair to try out, and I end up wearing them one night per month on my heaviest day. I like the extra protection and they are comfy! I have thick thighs so I was really worried about the hem being tight, but they fit super well and are so comfy. For context if you're ordering, I weigh 190 and am 5'5". I usually wear a size 12 jeans. 35" waist 45" hip.

    Work great and super comfy!

    These sleeper underwear are a must! I love how comfortable they are. I have been wearing these for nights and sometimes day for heavier flow days. Work great under a dress or skirt!
