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.

You can see our size chart here.

How to take care of your Period.

Rinse any fresh blood off in the sink or the shower.

Hang to dry then add to your laundry pile. 

Machine wash warm, no bleach.

Tumble dry low. Do not dry clean or iron. 

Each pair of Period. underwear can hold up to 9 tampons worth of blood.

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.

    Great as actual shorts! Ordered XS for S

    Wearing them literally as shorts, fits great, they looks like just nice bike shorts but they are for periods! Great quality and fast exchange if wrong size ordered,

    works great, size down

    I love period co panties. I've tried other brands but these are my favorite. They absorb great, rarely leak, and no PFAs, overall win! This particular style is great for first 2 nights which are quite heavy. I recommend sizing down. I usually wear a small to medium in regular underwear, and medium in most other period underwear brands but I needed an xs and could even go small with this style. I also really appreciate and love th customer service at period co, they are so friendly, accommodating , and generous. Thanks period co!

    I love these

    My review for the boxer underwear was long, so I don’t really feel like adding too much to this one, but these are great for sleeping in as sleep shorts or under sleep shorts 😅 plus they fit well. The only negative imo was that these feel a little bulky. But I get why and I get used to it after about an hour. That first hour isn’t too comfy though.

    Would buy again.

    I did not last as long as I expected on my heaviest days but no mess was made. My only suggestion would be to extend coverage further up the back and front.
