Reviews

Love these undies!

"I purchased the leak proof full briefs after doing much research! Just needed a little security during activities now I have reached menopause! They're comfy and easy to wash. Feel lovely on and are doing the job. Happy days!"

— Jane P. (5/5)

Soft and Comfortable

"These are my new favourite undies. They are super soft and designed in a way that hugs my body without being too tight in any spots. They have a comfortable amount of bum coverage and don't ride up. They are highly breathable so I never sweat in them. They absorb minor leaks easily."

— Sarah A. (5/5)

Great fit

"Fit well and don't feel too bulky. I only wear these overnight and they do the job. Take ages to dry though. Don't cut into the stomach either which I appreciate. I was using another brand for period undies but not anymore. Only boody now!!"

— Donna W. (5/5)

I've switched to only this brand

"I've tried them all. These are the best period underwear hands down. In perimenopause, I'm having to wear underwear with some protection more often. These are the most comfortable I've found."

— Michelle K. (5/5)

Love the soft waist band

"Other brands put elastic at the top while these you don’t even notice they’re so comfortable. They also just feel lighter and more comfy able all over"

— Yvette L. (5/5)

Comfy and does the job

"I had period underwear from a different company before and thought it wasn’t great; it leaked and wasn’t comfy. This one here is different. No leaks and no discomfort, it’s perfect. Feels like normal underwear and does the job."

— Melanie A. (5/5)

Comfortable and good quality

"I love these. They can hold up the flow for quite a while. It being high-waist means that there are no elastic bands tight on the belly during cramps."

— Paloma A. (5/5)

A Pure Essential

"Very comfortable and an essential for me when I'm on my period. Feels like I'm wearing regular Boody underwear. Honestly, I won't wear anything else."

— Rhubie (5/5)

Great but need to come up more at the front.

"Amazing comfort and feel. I just wished they come up more at the front of the pants. I lose a lot of blood clots and have over flowed out the front of the period pants. Please make the pants so they come up further at the front. That being corrected and id definitely give a perfect rating."

— Nadine (4/5)

Fantastic

"These are my first experiences with period underwear and I love them!!! Very comfortable and an all around great experience"

— kate C. (5/5)
