Reviews

Great but small crotch area

"I love these period pants. Love that there are no added chemicals and it’s made of natural materials. The only thing I would say is not perfect about them is how small/thin the crotch area is. The pants fit fine around the waist but where the blood actually comes out only has a tiny amount of fabric to catch it. It would be so much better if the crotch bit was wider for comfort and practicality. I’ve added a picture of a XS and a S for context."

— Ella (4/5)

Only buy for extreme flow

"These are really good quality and have lasted, however the moderate to heavy style are very thick and feel a bit like im wearing a nappy. I didn't realize when I bought them that I only need the light to moderate version as they absorb very well."

— Kaya (4/5)

Fantastic

— Catia B. (5/5)

"Really comfy"

— Shirley (5/5)

Perfect period underwear!

"These period underwear have the liner all the way up the back to the band to prevent those unavoidable leaks at night while lying on your back. Such a small detail that makes such a difference compared to other period underwear."

— Lacey J. (5/5)

Best period undies!

"These are by far the best period undies I have ever purchased. Would highly recommend."

— Melissa H. (5/5)

Would buy again

"I've been using reusable period products for the past 9 years and I highly recommend this brand. There are other good brands out there but these are soft and don't make me feel like I'm wearing an adult diaper"

— Sarah B. (5/5)
