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.

    The company in general

    I've used the $9 products from Walmart and loved them. My husband placed an order and just completely messed this up (reviewing from his name)

    I used the little chat feature and the person who helped was so nice, got the issues resolved. This company has the best customer service I've ever dealt with, and I will buy all my period products from them.

    So comfy!

    I love this, it's so comfortable to sleep in! If I got another, I would size down, I followed the size chart and these are too loose. I would wear them as shorts but not under pj pants, they are too bulky to layer. The only issue I have with them is that they are a pain to wash! Rinsing them sucks because there is so much fabric and I got a small, I would not be willing to rinse anything bigger.

    Great front-to-back coverage, but leaks on the sides

    I was pretty excited about these shorts, but they did fall short in my experience. They were looser than I'd hoped for (I ordered a S according to the size chart), and I think that's what caused the leaking onto the legs of the short. However, I don't think it'd fit well if I sized down, so I'm at a bit of an impasse. The front to back coverage was GREAT (I loved that it went all the way up the front and back), but waking up in the middle of the night to find the side-to-side leakage was disappointing.

    Best protection

    I have very very heavy periods and I usually leak everywhere. I had to wear adult diapers to try to contain leaking. I bought these with very low expectations hoping to save money. I am so happy that I did buy these because they hold alot of blood and I haven't had any leaking. I now can sleep without a diaper and a towel and I am saving so much money.
