Reviews

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)

Very comfortable and reliable

"I suffer with endo and extremely heavy flows. I usually hate wearing period underwear especially when sleeping but I was obviously just wearing the wrongs brands till I discovered this one. No leaking, very comfortable, doesn’t loose its shape after multiple wears and washes."

lara s. (5/5)

Comfy but improvement needed

"Comfortable as all Boody underwear is, but disappointing the leakproof insert doesn't come up higher at the front for better coverage & security. The coverage of the leakproof panel needs to be more clearly stated in all Boody period underwear, as photos do not display this."

Justine M. (4/5)

Nice period briefs

"First time using period briefs and it was better than expected. The padding covers a large part of the briefs and it was very easy to clean it. The padding does get a bit warm after a while. Still, the briefs are very comfortable."

Paloma A. (5/5)

Absorbent and stay fresh all day
