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

Great race day solution!
Fit great! Ordered for a 15k I was running and had no problems! Didn’t roll, didn’t make me super sweaty given the lightweight material, and no leaks! I typically wear a size 18-20 and ordered according to my hip for best fit.

Comfortable, lightweight, fit true to size, the padding is a little shorter than I'd prefer
These would be perfect if the padding went further back, personally. I use them as backup on heavier days, and on their own on lighter days, and I'd just prefer if the padding was longer to help ensure leaks would have a harder time getting past it. Otherwise, they're super comfortable to be in all day, and they fit true to your normal size in underwear. I really like the high waist v. bikini cut or lower cuts, and these ones have a nice high waist cut. I washed these in cold water and air dried, even though it says you can dry on low, and I'd recommend air drying to be safe. I feel the padding could be affected in the dryer even on low. I'd definitely recommend these.

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.

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.

Best leakproof underware
These are the nicest leak proof underwear I have ever bought! They feel like you have nothing on. Doesn’t smell as long as you don’t have huge leaks. I just have drops from time to time

Leak proof
Knox super leakproof high rise panties are wonderful & protect you from unexpected leaks & bowel movements.

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.

It is very comfortable. Also pleased with the absorbency for light leaks!!!

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.

Bought 2 sizes as I was not sure of fit. I do find they run on the smaller side. The fabric is not very breathable but does stretch enough that I can still use the smaller size as an emergency pair. That being said, the absorbant portion of the panty is quite thick and gives a bit of a diaper feel, and was not long enough to give proper coverage for me. I still ended up with leaks in the front and back anf def could not wear for sleeping. Would not reccomend.
