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 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,

    comfy and functional, but big and unflattering

    I want to love these! I’ll start with the good - I love this company, I love the fabric, I love the thoughtfulness, I love the price point. They are comfortable and they work, for the most part.

    Unfortunately, the sizing definitely runs large! The XS fit me like a S or even M…and my standard size is XS-S. For these to fit properly, I’d need an XXS Period Co sizing option, which doesn’t exist. I really don’t like the vanity sizing that y’all have opted to use, it’s confusing and misleading.

    Because these are too big on me, they are not tight enough where they really need to be to stop blood from leaking out of the gusset and dripping down my thighs. They are too loose in the lower booty. The bottom thigh band is wayyy too loose for me, with a major open gap at the bottom - about 2” of extra fabric. I want them to fit snug and securely, so I can trust that they won’t leak.

    For now, I’m going to attempt to shrink them.

    Please adjust your sizing!

    Very secure

    I accidentally bought two of these and don’t regret it! I can wear them as normal shorts which I have to get used to (wearing shorts without underwear) but they’re very comfortable to sleep in and don’t worry about any leaks. The only downside is they are a little bulky and I can’t really tell which is the front or back without the label.

    I ordered a large by following the size chart but they just fit really odd on my body. It feels like there’s no stretch in the butt and I don’t think I have a very large backside. I would recommend a size up
