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 to take care of your Period.

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.

    INCREDIBLE.

    I was previously buying the Victorias Secret period boxers, but on heavy days or nights I would leak from them. I have ovarian cysts and PCOS so my periods are H E A V Y. I kept getting ads for this brand and finally caved and ordered some about a year ago. I got the sleeper shorts and a pair of the briefs. These are seriously a life saver for nights 1 or 2 when flow is the heaviest, and they're nice to just wear around the house. They also wash GREAT unlike some other brands that fall apart, I've had mine for over a year now and they're still like new out of the wash. Seriously cannot recommend enough!

    Very comfortable and easy to wash! Although make sure you can either dry it in the sun, or a place that will dry is quickly if you hang it up to dry because it will get that musty smell clothes get when they are wet for too long.

    Front leaks

    These work great if you don’t experience front leaks. The absorption material doesn’t go far up enough in the underwear. I leaked two days wearing these at work. I like the boxer style better which is why I tried this brand.
