[This review was collected as part of a promotion.] Don't let the thong scare you - these undies are amazing! They're extremely comfortable with no "diaper" feeling. You could easily wear them off your period and feel no discomfort at all. As for absorbency, I had zero issues. No leaking, no spots, nothing. Washing it is also extremely easy, as well! I would highly recommend it as an addition to your period lineup.
Lightweight and super absorbent

[This review was collected as part of a promotion.] These are great for people with a light flow or for the lighter days. I personally use these in place of a panty liner. These are also perfect if you prefer thongs rather than fuller coverage underwear. The material is very light and breathable. They feel like they will last a long time even with constant washing. I tried the beige color but I’d prefer the black. It’s super absorbent for the light one.

[This review was collected as part of a promotion.] Pretty comfortable, this thong is really good to wear either right before your period or towards the tail end when you're still spotting. I got the extra small, and as someone 155cm and about 44.5kg, it fits pretty well. I've worn it a couple times, and it seems pretty durable. So happy to have something pretty to wear even when I'm waiting on my period to start.
Love them!

[This review was collected as part of a promotion.] I have received Proof Reusable Period Underwear in exchange for my honest feedback. It was my first experience with period underwear and, honestly, I was skeptical at first, but these light period thong have completely exceeded my expectations. I love them after the first time I used them and can't understand now how I lived without them before. As someone with a light flow or just looking for extra protection with a tampon or cup, these are perfect. The fit is sleek and super comfortable—just like regular underwear, but with way more peace of mind. The thong style is a game-changer for wearing tighter outfits. They don’t bunch up or feel bulky at all, and they look and feel just like my favorite pair of underwear. Best part? No leaks, no odors, and they're surprisingly breathable. I’ve even worn them during workouts without any issues. They've held up well after several washes, and I love knowing I’m reducing waste every month. I honestly wish I’d made the switch sooner!

[This review was collected as part of a promotion.] I like these period thong underwear for their absorbency and discreet look—perfect for light days or as backup with a cup or tampon. They fit well and feel secure. The only downside for me was the crotch area—it felt a bit stiff and slightly uncomfortable at times. Other than that, they do the job and are a great eco-friendly option!

[This review was collected as part of a promotion.] This has been the best discovery for me, as it is very comfortable and eliminates the need for extra pads. It saves money. It has excellent absorbency, doesn’t leak, and effectively controls odor. The fabric is of very high quality and firs so well on me, providing great comfort even on difficult days. I highly recommend it.
Just not a correct fit

[This review was collected as part of a promotion.] The Proof Reusable Period Thong I’m a size XL and these were not a tight enough fit on my hip area. They sure didn’t feel secure enough on me to stay in place. The fit was really weird to me and kept feeling as if they were slipping, the period collector area didn’t want to stay in correct place because of this. I sure wouldn’t wear these on heavy flow days as I just don’t trust them that well enough not to spill out, over and just become a full on mess. The summer time sure made these sweaty feeling too and not really like they would breathe. I wore mine with a dress and was thinking it would be ok but the whole time I felt like a hot mess express just one mishap of an accident about to happen with these. I’m thinking maybe a better fit and I could totally use them but for now these are not for me!

[This review was collected as part of a promotion.] Comfortable fit, breathable, and stretchy. The absorbency pad is big enough so you don't have to worry about leaks on your lighter days. So easy to use and wash.

[This review was collected as part of a promotion.] These panties are great for light period days. I enjoyed using them on the last few days when I am experiencing spotting or a lighter flow and don’t need to wear a whole pad. They are fairly comfortable however, the fit is a little bit strange. The lined section lays on the body in a rigid shape. These also ran large on me. Because of the fit, I would recommend wearing these with loose clothing rather than tight clothing. I think these are great for those days when you need peace of mind as your period begins to end.
Perfect thong for time of the month!

[This review was collected as part of a promotion.] These only get any stars at all bc of fit and ability to remain undetected under shorts. They are comfortable and show minimal lines. However they were not absorbent. I am postpartum and not getting periods but I wore this underwear outside on a hot day. They didn’t even absorb sweat and discharge without feeling wet. I also remain skeptical of the safety of the ingredients used to make this underwear on such a sensitive part of the body. I feel underwear should have a cotton crotch. These are made of plastic and who knows what else is in all those finishes. Do not recommend.

[This review was collected as part of a promotion.] Unfortunately, received a size too small. However, it seems like these are a great option for light days or spotting. I can’t confirm total absorbency since the fit was not right. I think these would also be a gray option for wearing during workouts or any athletic activities. Seems like a comfortable fit if the size was right.

[This review was collected as part of a promotion.] I was always weirded out by the thought of period panties, but I was pleasantly surprised by the effectiveness of these, they did run a little small on me, but even with that it felt like I was wearing nothing. The material is super soft and smooth and the absorption surprised me. I'll definitely get more of these
Super comfortable!

[This review was collected as part of a promotion.] I have been wanting to try a period underwear product for so long!! When I saw there was an opportunity to try this, especially a thong, I was VERY excited. Not only did these work great for my lighter days, but I feel great knowing I’ve got a backup of a leak occurs. As someone who doesn’t wear anything other than a thong, I was happily surprised by how comfortable these are (I have tried MANY thongs). I will definitely be purchasing more and might even get the regular cut ones for sleeping! I highly recommend this product!
It works!
