★★★★★HavvaI've tried several brands of period underwear, but this one really stood out. The coverage was noticeably better, offering more security—especially on heavier days. The fabric felt like higher quality compared to others I've used, soft yet durable, and it held up well after washing. It offered reliable protection without sacrificing comfort or style.

★★★★★FrancesI’m so grateful to discover this brand! I have been wearing period pants from other brands for years but have never found any that are perfectly leakproof — until now, thanks to these classic briefs from Fri Period! For the first time in forever, I now have a reliable pair of period undies where I don’t need to have backup pads on hand. I can wear these with confidence all day long.

★★★★★NoelaI'd been wanting to try period underwear and then a friend got me these. I was nervous at first but they absolutely do the job and are so comfy to wear. Washing is easy and they come out like new each time. Plus the print is really cute. I'm def gonna get more!

★★★★★RebeccaThe last thing I want on my period is more discomfort. This underwear has made this time of the month so much more comfortable.
★★★★★MeganI waited to go through two cycles prior to reviewing. I wore the underwear on both a medium/light day, as well as on a heavy day. They are very comfortable and held everything in with no leaking. They are easy to care for and washed well. It is great to purchase a sustainable product that is also packaged in sustainable, compostable packaging! I will definitely be purchasing again!

I sized up, as suggested by a friend, and am very happy with the fit. I went for the size XL and I am normally a US size 10 (AU size 14). This style (the Classic) provides nice full-bum, high-waisted coverage, and gives me the secure feeling I have been craving from period pants. I am especially appreciative of the additional front coverage. Front-bleeding is a thing! No other brand seems to cater to this and I constantly leak out the front of the gusset (and sides) in other brands — and finally these do cater to this and there have been ZERO leaks — hooray! I have now gone and ordered a bunch more and can do away with my old period pants from other more-expensive, well-known brands. The cotton fabric is really nice and soft too. I'm a total convert. Thank you, Fri Period, for creating these.

My period has become so easy and very comfortable after buying those!!
Definitely gonna need some more!
These are my new faves. I’ve tried a few different period panties but Fri Period is the nicest - the material is soft and the print on the inside is a nice touch.
I waited to go through two cycles prior to reviewing. I wore the medium-heavy flow full brief underwear on both a medium/light day, as well as on a heavy day. They are very comfortable and held everything in with no leaking. They are easy to care for and washed well. It is great to purchase a sustainable product that is also packaged in sustainable, compostable packaging! I will definitely be purchasing again!
I bought a pair of these for lower flow days, and they work perfectly! So comfortable for all day/all night wear, no leaks, no odour and no worrying that other people know I'm on my period while I'm wearing them as there are no unsightly bulges! I've also washed them loads of times now with no change in their quality- would recommend for anyone looking to have a more sustainable and comfortable period.
I absolutely love these period panties! I ordered a medium and they fit perfectly. I am normally a size 6 in pants. I ordered the medium/heavy flow and I was able to wear them overnight and throughout the day without any worry. They are very comfortable and keep you dry. I 100% recommend these. I will be purchasing more!
The product is awesome. I was holding off providing a review because I wanted to see how absorbent it was... turns out, I couldn't tell, because it's so incredibly absorbent!!!! They are miles comfier and cooler than modibody, which I had before.
This was my first time trying period underwear and I'm a convert. I was reluctant to try before because I thought cleaning them would be a hassle but it's so easy. The actual panties are really soft and the padding doesn't feel at all bulky. Quality is good and I love the eco packaging. Will buy again.
I am blown away by the comfort of this underwear. They don’t feel bulky like some other brands do, and they’re so much better (and more secure) than wearing pads! I’m spreading the word about this brand. They’re a lot less expensive than other brands I’ve tried which didn’t perform as well.
I love the comfy ,stretchy yet secure fit ! Especially for bedtime hours! Great absorption and great with odor free
The material and how they feel when you wear them. They are comfortable
I Lovedd the panties. I have tried them as both leak protection and as overnight period underwear. they are breathable, leak proof, and don’t show beneath jeans.
