I'm extremely happy with my period underwear! I can't believe how much they absorb, and I felt comfortable and, above all, dry all day long! I bought 5, but if I need more, I'll definitely get the same ones again.

Customer Reviews
Overall rating: 4.9 / 5 from 146 reviews.
Amazing and reassuring. For the past 3 months, my periods have been longer and heavier than ever. My old period underwear wasn't enough anymore, even though it was ultra absorbent. I searched a lot for other period underwear, and I came across Orpair. It's the only shop today that offers this type of underwear for super heavy periods and postpartum bleeding. I went straight for the pack of 5, with 2 free, and I'm extremely satisfied. Now I can feel relaxed all day long without changing.
The product is amazing. My daughter, who bleeds a lot, is thrilled. The period underwear lasts all day long.
Very soft and very pleasant to wear. It doesn't squeeze around the belly but adapts to your current shape. I have a heavy, sometimes hemorrhagic flow, and I finally dare to go out or go to work in my period underwear.
The period underwear more than does the job, and it's pleasant to wear on top of that. I'm amazed at how fast it absorbs. I didn't expect it to be so instant!
Very satisfied with this period underwear for the end of my pregnancy. The fabric is soft and pleasant to wear. It comes up nicely and stays in place around the belly.
My daughter is thrilled and feels confident.
Hi, I'm getting back to you as promised... I've never slept as well as I do with your period underwear, and yet I have really heavy periods ++++ Thank you to the whole team You're the best 🫶🫶🫶
I'm more than thrilled with this period underwear. I stay dry all day long, even on the first day of my period. Great experience. I recommend this model.
Very comfortable period underwear for hemorrhagic periods. I love them!
They're ultra comfortable
Very satisfied with my purchase. The period underwear for hemorrhagic flow does its job perfectly. I recommend it 100%.
I've been wearing period underwear for several years now. I've tried many brands, and I decided to give Orpair a shot after seeing an influencer. I have VERY heavy periods, and to this day, no brand has managed to survive the 2nd and 3rd days of my period. I didn't have much hope, but this underwear exceeded my expectations! For the first time, I've found underwear that can handle the worst part of my cycle. I'm very satisfied and relieved. So THANK YOU!
Great experience! The product seems to be high quality and the delivery was great! I'm waiting until I give birth to use them!
Fits perfectly and is really reliable!
Great
All good, nothing to report.
The postpartum period underwear is very comfortable, very absorbent, and doesn't squeeze around the belly. I recommend it after giving birth or getting a copper IUD!
Fits perfectly and is so soft around the belly. It's just as good as the boyshorts and is really comfortable.
Great! Very comfortable, I recommend it.
Pretty, pleasant, and protective
Very comfortable and very absorbent. I recommend them.
Wonderful I have a super heavy flow and it really works. Very happy, I'm going to order some for my daughters too.
Great! Nothing to say! Perfect comfort! I wouldn't change it for anything in the world! And the customer service is just top-notch Bravo 🎈 I recommend it 100000%
Very comfortable product, I highly recommend it!!! It's perfect.
Thank you
I really have a very heavy flow, and I was able to relax all day long without worrying about my underwear. No odors, no leaks. Just perfect.
Good
Excellent customer service, and the period underwear is fantastic!
Very good
Period underwear that's very pleasant to wear and holds up really well despite hemorrhagic periods! Thank you Orpair!
I had ordered a size that was too tight, and I was able to quickly get an exchange from customer service. My daughter, who had leaks with other brands (S..R...) despite their "super" absorption, now feels very comfortable and confident in the postpartum period underwear and is asking me to buy more, because it lets her get through a school day with total peace of mind. So, a pretty positive first experience with the brand.
They absorb really well
After trying 3 brands, I found this period underwear for hemorrhagic/postpartum flow, and I'm very happy with it. Even though, unfortunately, it only lasts (for me) 7 to 8 hours max, that's still a relief, because with other brands I was down to 3-4 hours. So I'm very happy. They're also very comfortable and soft. Received quickly and very well packaged. I ordered 2 sizes up because during this time you're always a little bloated and you need to be comfortable and not squeezed, and also because with other brands, after several washes (at 86°F), they shrink a bit, so just in case... They're super stretchy and fit well despite those 2 extra sizes, and I still don't look like a sack of potatoes 😅. My only wish would have been a version that comes down a little further at the crotch (since that's the first spot that overflows, because that's mainly where all the flow goes), while staying very stretchy so the seam doesn't bother you over time, since that's the first spot that overflows. So I'm very happy with this find. Thank you, it's a relief not to have to think about it all the time.
I had already bought period underwear for heavy flow, but I had a few leaks. Although a little disappointed, I gave it another try with the period underwear for hemorrhagic flow, and this time it was a great experience because I had no leaks at all. Really suited to my flow, and the size is right. The feel of the hemorrhagic underwear is much more pleasant than that of the Julie ones I ordered previously. I haven't had the chance to test the period boyshorts yet.
Easy to order, fast shipping, quality.
I bought this period underwear for my daughter. She's very happy with it because it handles her heavy first-day flow perfectly, and it's very pleasant to wear.
Very, very absorbent period underwear. Fantastic.
Perfect period underwear, now I just have to try it when the time comes.
Perfect! Fast and careful shipping, the order matches the description perfectly, and they're of very good quality.
Built for your heaviest days.
