    Excellent coverage and very comfortable

    Sometimes, as women age, we laugh and pee ourselve a little and it's not that funny. This underwear offers the most comfortable and affordable (think of the savings on disposable pads!) coverage while also wicking away sweat from excess chub rub. Definitely a Knix-convert for life now.

    Honest review

    Yes they are comfortable. Less hitchy instead of pad. Finally we get a high absorbing material on the front. For my case I bleed more in front instead of back.

    But, The back don't stay tight at the skin. So is like having something not fix who follow movement. The underware feel like floating. So I put one of my underwear over, to keep everything in place.

    If the underwear will be more thing at the butt, I think that will be the best improvement. But for now, that what I dislike of this.

    Total game-changer

    I was definitely skeptical at first about trying period underwear, but taking the plunge was honestly one of the best choices I've made. They are surprisingly comfortable, completely leak-free, and feel just like regular underwear. Not only did they give me complete peace of mind, but they're also a total game-changer for sustainability and comfort. I will never go back!

    These would be great if you didn’t wear pants

    For many women, these types of underwear are a necessity, and I do appreciate that companies like yours exist. I’ve been on the hunt for underwear like this for over a decade.

    That being said, for the price point, it’s unbelievably frustrating to receive underwear that shows through all of my pants and cannot be returned. Unfortunately, the design feels extremely flawed. Not only do you get a regular panty line, but you also get a pad line from where the leak-proof material ends. The leak-proof layer should expand over the entire panty so you don’t end up with double lines in both the front and the back. There is also folding and chunking of material right around the groin area, making it very obvious what you are wearing.

    Women want to remain active, go to the gym, and exercise. Being able to wear protective underwear allows us to do the things we enjoy without feeling like we're missing out. Unfortunately, these don't make the cut because you cannot wear them with gym clothes—they are best suited for loose sweatpants where panty lines don't show.

    It’s extremely frustrating considering I ordered three pairs, spent over $100, and now cannot return them.
