★★★★★
I’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.

I'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.

The last thing I want on my period is more discomfort. This underwear has made this time of the month so much more comfortable.

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 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!
