High Absorbency for Heavy Flow Period Panties; Leakproof, for Teens and Women

I'm a female athlete, an endurance runner and as of late a power lifter/strongman in training. Any female athlete can testify that training on your period is the pits. Tampons slip. Pads are wretched...just UGH! But if I wanted to continue training through my period I had to find an option that worked. So after shopping around and seeing many unaffordable options I found this product. I read through the reviews and thought hey lets give it a shot.My Findings:I measured my hips with a tape measure and purchased the size based on amazons recommended size chart. The fit was perfect for me. A girl who is a little "hippier" might want to size up, but I have skinny little European white girl butt and they were fine.Because I didn't want to compromise the product i followed the recommended washing instructions to a "T". So day two of my period, it is a heavy flow day and today was heavy squats at the gym..Perfect first time, test run. I wore the panties with no other hygiene aids, just the panty and my exercise spandex. You could barely see a pantyline. Other reviews mention "loud plastic noise" Not an issue during wear I found. The "noise" was equal to if i wore a maxi pad so no big deal. I was able to get my full work out in with no discomfort or unplanned bathroom breaks. Best of all, no smell, no leak through! My training session was an hour and 30 minutes long. So I come home, get ready to shower. In the panty I notice a significant amount of moisture in the crotch, probably combo blood and sweat. Since I'm not one to waste electricity or water- for prewash care I rinsed them in the sink of cold water, put Hydrogen peroxide on the crotch since it's a great blood/bacteria cleaner, then rinsed in cold water again. No smell while they are waiting in my delicates bin for the next full wash cycle.In Summary:They more than served the specific purpose in which I bought them for. I probably wouldn't trust them for all day protection or overnight protection without a tampon on heavy days. But for light days and workouts-WINNER!

UPDATED November 2, 2020The design of these have changed, and so has the feel and fit. I bought more because, hey, a girl needs period protection, and underwear wears out over a few years, right?ANYWAY. These new ones are fine. I feel like they’re thicker, somehow... but the weird swish noise some people have pointed out seems to be gone now. The fit is FAR looser, so buy your actual size. I got XL and I wear a 14/16 women’s pant.Functionality is basically identical. No leaks, no worries, no shrinkage after washing. It’s so nice to never have a liner or pad to toss. Save the environment and save my laundry from leaks, win-win!***Original review December 2018:***These are fantastic. I ordered a little bigger based on other reviews, and I think I could have gotten away with my actual size, but they might have been tight in the leg holes (that sounds SO weird but whatever). I use a menstrual cup and these are my life changers so I don't have to use liners all day every day. I have PCOS so my period is ridiculously painful and my uterus loves producing so. much. detritus.ANYWAY. My cup isn't enough to hold all the fluid for more than two hours on a couple of my heaviest days, so I leak. These panties save my clothing and my peace of mind. They're comfortable. I've washed them, they're fine and keep their size well.

This was my first experience with period panties. I have a medical situation that makes it uncomfortable to wear tampons or cups right now, and I really hate pads. This seemed like my best option, and I am glad I tried it.I don't think they are meant to be worn alone, but I have a lighter flow, so I got away with it for most of my cycle. They were comfortable and absorbent. I had to wash after wearing the first three pairs, because they have to air dry after washing, so I couldn't expect them to dry while on my last pair.They do swish a little when walking in pajamas but I don't hear it under jeans.They are a little hot, but sweat is absorbed. This may be TMI, but farting in leakproof underwear is a weird experience.Overall, these are fantastic. My cycle is no fun, but they made part of it easier.

Amazing quality for the price, and half the cost of thinx. I own the hiphugger thinx but one panty isn't enough to get through a whole cycle and the price tag on thinx is too high to get more. The thinx panties don't have the absorbent material in the front but these do. These also cover your whole behind unlike my hiphuggers. I think these could fit any body type because the material is so form fitting and the elastic is the perfect amount of stretch and does run true to size. The leak proof PUL material in these is exactly the same as my thinx. I poured water on these to test that they absorbed and they held up. Just like with pads, clots will take some time to absorb. If it's big I'll just wipe it off with some toilet paper. No big deal. The only difference in these and thinx is thinx uses polyester and nylon on the non absorbent part, and these have organic cotton which I much prefer because it isn't as hot and far more comfortable. There was a bit of a swish sound while walking but it seems to lessen after some washes. I looked around at some Asian brands but I only wanted black so there would be no staining and didn't want to hassle with sizing returns. My periods are all over the place so sometimes I'll have a very light flow and can get by on just the panties but other times it can be very heavy and I'll have to use their reusable pads as backup. They are great for working out too if you don't want to show sweat and they stay put. These and the reusable pads are the best purchase I've made for my periods ever.
