Worth every penny
I had used these before also loved them. Recently lost weight and first bought new underwear for myself that were not “leak” worthy. That’s why i use not for period… Anyway after couple of months i realized i need this so i read the description for sizing carefully. As i still have the ones from before i lost weight. They were just too big. All the comments seem to say that they liked how it felt the fabric, etc. so I decided to give a try. I only ordered one pair even though I knew I would want more if I did like them so I read the sizing and I determined that I would be a medium, but I kept thinking if it’s wrong and they’re too small, I would not be able to handle that so I just bought one pair. I also read in a reviews that somebody was able to return if they started to bother them because somebody said they bothered them in the leg or something and they were able to return. I don’t know if it was this specific type I forget, but Anyway I bought one pair they came and I have to say that these specific ones really hold you in if you’ve got loose skin in your belly number one very smooth there’s no lumpy bumpy anything. The leg is completely comfortable and it ends right where my butt does and they really are absolutely perfect. I do remember when I had them in the past, I had a pair that looked like they had like a gold design on black and then I had another pair that were beige like this type that I just bought And they definitely had a different feel so that’s why my review is for the beige specifically of this specific item, I just remember noticing that even the same size same style, the fabric and color sometimes made a difference. I don’t know why, but it did so everybody needs beige underwear. These are perfect and read what it says about sizing. I wear a size 10 jeans and I am a medium and they fit like a glove. And I’m pretty sure I paid more for these when I bought them in the past so even though it’s pricey, it’s not a terrible price and it’s worth it because first of all they work for the reason you might be buying them and second of all, they’re extremely comfortable and third and foremost, they hold your belly and your butt secure and comfortable, no jiggling

Nice insurance in case of a sneezing or coughing fit
Didnt expect to like these but it sure is nice not to have a leak when you are out and about all day and have a giant mega sneeze or coughing fit. They feel comfortable, are no show, and wash well. Expensive, but work well especially if you are away from home a long time.

Great product!
I was hesitant to get these because of the price, but I caught them on sale. The fit is excellent. I’m 5’5”, 170lbs, thicker around the middle. These feel great and don’t roll down or ride up. I use a Saalt disc with maxi pads for back up on my heavier days, but I hate the feeling of a pad and have used cheaper leakproof panties at night (not seamless and pretty lumpy😂 so not a good look for leaving the house!) so I wanted to try some during the day after a recent gusher experience at a theme park 😱. I now wear these panties as my “backup” on heaviest days instead of using a pad, which just feels gross. These panties solve the problem. They are super high-waisted, perfect for dresses or clothing cut specifically high-waisted. They do show about a half-inch above my scrub pants, but my top is long and covers it. As a primary method of period protection, I anticipate the gusset may be a bit short both front and back in this “super” version, but the “ultra” leakproof with a full gusset isn’t available through Amazon currently (I like to avoid shipping costs, so I didn’t purchase direct from the vendor.) Definitely recommend. I’ll watch for another sale!

Yes yes yes
True to size. Was looking for an alternative to the Uniqlo ones because they’re sold out. These are great! Fit great, keeps you comfy all day and night! I do wear a liner with them. I don't wear them completely bare unless it’s an emergency or on a non-heavy day.

Absorbent gusset not long enough to protect from leaks!
This appears to be a well made product. It is thin which is what I wanted. Unfortunately deducting two stars as they are intended to be period panties. The absorbent gusset (again well made) would only work for light days. It is way too short in the front and definitely in the back. If you slept in them on a heavy flow day, they would 100% leak because the gusset is exactly like regular panties in size. So for their intended purpose, I will be unable to use them except for the final day of my period.

Knix super leakproof panties
I bought one pair. I used them at work yesterday. Aug 2023. I have a little issue with bladder urine leak. I wore them for 8 hrs. They did well. I was surprised. They were comfortable light I didn't know I had them on. First time I haven't wore a pad to stay dry in a few years. It was freedom from the pad. Felt good to feel normal again. Not chained to a pad for once. I can see how you wouldn't want to use them if you have more than a little bladder leak. But for those every so often sneezing issues or that small gush they work ! Thier not cheap. But I bought 3 more. So I have 4 pair now for work week. Thank you knix. 😊

Too pricey
The color, fabric, and fabrication is nice. The fit is good except the leg opening is a little loose on me. I have not made a scientific test of the claim of absorbing 8 tsp liquid, but somehow I doubt this claim. I ordered these for urge incontinence and they don’t seem any better than a long panty liner. At $36 each, I won’t re-order.

The fabric was very smooth. They are a looser fit than I was expecting, but very nice.

Not thick fabric, but does not feel cheap. Seams are heat sealed, comfortable. Lays smoothly under clothing. Following the size chart worked. Did not shrink in the wash. Absorbent layer does not go far back, so no sleeping on your back in them with heavy flow. I am keeping them.

The gusset on these waterproof panties felt quite stiff, which made them a bit less comfortable than I expected. While the overall design is practical and the waterproof feature works well, the stiffness in this area may take some getting used to. It could feel restrictive during extended wear, especially if you’re moving around a lot. Aside from that, the fit and coverage are good, and the material seems durable and well-made. If the gusset were softer or more flexible, they would be much more comfortable for daily use.

These are great and worth the price because you can wash them. I do crossfit and there are certain exercises where the momentum can cause issues and the lining works perfectly, no leakage and the fit as a whole is really comfortable. They were recommended to me by other women in the gym who use these. A big plus not having to use pads.

The underwear is expensive, which is why I only ordered 1 the first time. Once I tried it out and found out how dependable it was, I ordered 3 more. For anyone with leakage issues if they cough, sneeze or laugh, this underwear works really well. Even when I had a cold with a cough, I could sleep worry-free all night.
