Reviews

Best Period Underware so far!

"I have tried Thinx, Period Co, and now Boody. Boody was by far the most comfortable and gave me the best sense that they were as natural as possible."

— Sarah F. (5/5)

Best period underwear ever

"Ever since I had chronic hives, period had been a nightmare for me. The usual sanitary pads and panties gave me angry itchy hives all over my hip and thighs each time and lasted at least a week. I tried several other brands of period underwear but they were either cutting into skin or non breathable. I discovered Boody at a pharmacy while on a holiday in NZ and it was a life saviour! No itchy hives during the trip and also on the 10 hours flight back home. I did not even realise it was there. What a great invention!"

Period & Leak Proof - Full Briefs - Moderate - Heavy - Black

"I was very excited to get my cycle after receiving these haha! They are hands down the most comfortable period panties I have tried so far. I love how high the gusset goes and just how breathable and that they actually stay up and I'm not constantly pulling up and adjusting them."

— Sophie T. (5/5)

Soft, comfortable, and no leaking

"So far I haven't had any leaks using these both during the day and sleeping. They are very soft and comfortable, and they don't make noise like normal pads do when you move around. The reason I chose this brand is because I have sensitive skin, pads give me rashes and both pads and tampons tend to use lots of chemicals and plastics. I liked that they use as much sustainable materials as possible while still being soft and stretchy. The only thing I will say is that drying time takes forever, so you can't use the same panties in the same period. It took several days for my last pair to air dry after washing. So I ordered more so that I can wash them all at the end of my period instead."

— Lexi (5/5)

Game changer

"Comfortable, practical and makes periods just that little bit better. Would highly recommend for comfort, function and materials used in the product. Much better than other alternatives out there."

— Kirrily C. (5/5)

Comfy period knickers

"Fabric and cut are soft and comfortable."

— Angela W. (5/5)

Happy customer

"I had to buy more period underwear as my previous ones either leaked or felt uncomfortable especially when having a heavy period. I have just tried out this brand and I could not be happier. I went for the heavy flow underwear as my cycle can be unpredictable and I can now report that as well as being comfortable to wear for long periods of the day I have had no more leakage or staining my clothes to worry about which is a weight of my mind."

— J C. (5/5)

Great investment

"Super comfy and great for sensitive skin, no odours and easy to clean"

— Olivia D. (5/5)

Feel confident with these!

"I feel confident wearing these, especially during work and exercise! The sit perfectly with comfort and softness! They keep their shape and softness after washing and drying!"

— G (5/5)

Secure and soft.

"Very please with these. They’re very comfortable, nothing is too tight or too loose, and the band sits right where I need to to partially hide that period bloating. I’ve used these both with reusable pads (for which these period pants are well suited) and on their own, and in both cases I found them to be secure and soft."

— Sudevi (5/5)
