Worked Great at a Waterpark
My daughter used these at a waterpark while on her period. She is 5'4" and weights 125 pounds. We bought both the small and medium. The small fit best as the medium bottom had gaps around the legholes. The key is you want them snug against the leg area so they don't leak. They are higher cut and don't have full bottom coverage. They felt a little skimpy to her so she wore shorts over them, but also just in case there were any leaks. She did mention that she did have a bit of "orange color" that leaked out from them. But, they definitely came to the rescue because otherwise we were not sure how to go to a waterpark when her period hit. They have a 1/4 inch sewn in pad that is also black that is the crotch of the bikini. After the park, we threw them in the wash. I would recommend them as an alternative to girls who don't use tampons. Expect a bit of leaking, but other than that, they saved the day!

Worked great! No leaks!
I was on my second day of my period which was pretty heavy flow and it was the 4th of July, I had planned to go to the beach and was not going to let my period get in the way of me going to the beach. When I was in the water, the pressure of the water obviously stopped my period for a little, but once I exited the water I felt some flow but no period leaks occurred, it held most of my flow for the 11 hours that I was there at the beach. Very impressed, had high hopes for this product, and worked great for me. However, wish the price was more reasonable or at least sold at larger quantities for the price. I would buy again if needed or if more colors are added later on.

Size up!
These fit rather small for their size so I would definitely recommend sizing up a size or two! I normally wear an XL but these fit more like a medium or small large. I bought this to wear during some cruise excursions where we'd be swimming in cenotes and caves and I knew I'd be lightly bleeding during that week. I think they did a good job though I'm not sure how they would hold up if I was going heavy. My daughter also got a pair. She was bleeding heavier and ended up wearing a tampon with them because she was worried about how small they were. They did a good job helping her as added protection. They look and feel very much like normal period underwear than swimwear. We wore ours under our suits instead of as bikini bottoms which worked out fine.

Worked perfectly for my active daughter
We bought these last minute to use at the water park. My daughter wore them under her swimsuit. We were at the park for about 5 hours, swam in the wave pool and went on multiple slides and no accidents. I think the key is to make sure they are a snug fit around the thigh and butt to prevent any leaks. Great purchase!

Feels like I have a big pad on!
These are not bad if you NEED to wear them for a heavy day but you can see where the "pad part" is sewed in it bc it looks thicker if that makes sense & it feels like a pad is in it too. I am keeping them though because I would def wear them if I need too as a back up.

Filthy NOT NEW
Zero should be a rating because that’s what I would give this item. I received A filthy pair of black, bathing suit bottoms that look like they were drug around on the floor of a factory for a week! Beware DO NOT BUY!

My kid needed them as she went to a beach trip with her friends and it happened that her period came 1 day prior. The underwear looks stylish and worked great. She wear it the whole day at the beach (4-5h) without any issues. It held the liquid great. Also, she could wash it and dry it for the next day at the beach. Both my wife and my daughter were amazed by how well it worked and recommended it to the other mothers present. The daughter played in the water a lot. Went with a paddle board, volleyball in the water and when she came out of the water, no issues. Amazing product. I recommend it! It was a play date saver! Ordered in the night and got to the cottage the second day around 1:00 pm.
