The High Waisted Period. in Organic Cotton For Heavy Flows
Super absorbent. Built for heavy days.
Absorbs 9 tampons worth of flow or five pads.
Hi! I’m super-super-super absorbent and designed to handle the heaviest days of a period. I’m made of soft, comfy organic cotton and have a four-layer padded towel absorbency that holds your flow. I have a wicking layer on top, so I can absorb the blood super fast with no wetness. You will feel padding, but frankly, on those heavy days, feeling secure, safe, and leak proof is a pretty great feeling, alongside being so comfy and cozy. Warning: after you use me once, you will look at tampons and disposable pads and pretend you don’t know them. Be cold. They deserve it.
When to wear: on your heaviest days. Also great for postpartum and perimenopause.

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 Coral Reef: Hi! Thank you for using non disposable products. It may feel like a small gesture - but it’s not. I’m sick of getting tampons and pads getting caught up in my beautiful branches and you’re helping to keep that trash out of my home. Just one pair of Period means that 5 pads/9 tampons are never used or thrown away. Thank you! Next time you swim by me, stop and say hi.
