1 pair absorbs 2 tampons of flow

For Medium to Light Flows. Designed for all sports and everyday activity, and yes, a thong!

Absorbs 2 tampons worth of blood. 

I’m the Sporty Stretch thong. I mean business. I’m a thong that can absorb period blood and I could do a triathlon. I’ve got the nice discreet feeling of a thong and the serious backup of being highly absorbent. Please play the Eye of The Tiger the first time you put me on. You’ll see. I’m made from our PeriodTech™ fabric - a super stretchy and comfy Nylon and Spandex knit that moves with you. As always, the gusset is made with organic cotton.  

When To Wear: For moments when you need a sporty thong, You will know those moments.

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 blade of grass: Hi! You might notice me. I am one of a trillion trillion blades of grass. But I notice you. With just one pair of Period underwear, you're saving the Earth from so much non-disposable junk. I have some blade of grass friends who live near landfills and let me tell you, slow decomposing tampons and pads are not pretty. Next time you see a breeze going through a field of grass, know that it's us waving hello and thank you at you.

    Absorbent pad too far forward

    So sad I wanted these to work out for the price but the absorbent part sits way too far forward. Sits about an inch higher than my pubic bone and only goes back maybe an inch from where the blood comes out of you know what I mean. It makes no sense I’m now I’m stuck with these. Photo with another brand for comparison. Their absorbent layer goes up the crack a little where period.’s stops at the seam at the bottom (gray pair)

    These used to be perfect

    Why change something when it works so well? Ugh. Took side by side pics of my sporty stretch thongs and these new ones are clearly a whole size smaller. Labeled right… but they definitely changed something to make these smaller. I hate them now… great.

    My new favorite!

    This thong is awesome! For working out (and getting sweaty) or for that last, trickle day of your period. It’s so comfortable and stretchy and high rise! And I love the gray color.

    Pad too far forward

    Tdlr: the pad literally fits like a cup and I’m a woman, but I hope the product gets redesigned because I like this company’s values and this underwear is otherwise perfect.

    These are perfect, except that the pad is way too far forward.

    The underwear has a seam right in the center of the gusset separating the front panel and the back panel. The pad is only on the front panel, so that when I wear these comfortably, the seam hits, and therefore, the protection ends, right where absorption is most needed!

    I really did want a thong option, so I’ve kept these and I try to make them work by adjusting the back way up and the front way down, but that means that the back of the underwear is very high and potentially visible, depending on the outfit, and that the front is very low and cutting into my legs uncomfortably. I always prefer to wear thongs and genuinely find them very comfortable, but the needed adjustments to this underwear makes it so uncomfortable that it really tests my resolve hahaha. While this is the only way to get any function out of the underwear, it also means that I have less leak coverage in the upper front.

    Overall, I’m trying to make these work, but I think I would have been in big trouble if I’d used them on any day other than the day after my period ended. I believe that if I’d had any spotting, I would have been out of luck, even with putting my all into adjusting these to work. I personally wouldn’t wear them while actually menstruating, even if I…

    Protective Fabric Too High Forward

    The protective fabric is too forward, so when the blood comes out, it's on the seam of the protective fabric and the "normal" fabric. Doesn't hold the blood well at all due to this. I love the bikinis from this brand, but don't recommend the thong at all.
