    Amazing!

    My husband encouraged me to get more of these! We are both happy with them (since he sees how happy I’m in them). The best period solution and so comfortable!

    I highly recommend them and am looking forward to relying on them in the future as well.

    soft, warm protection

    I am 5'7" about 153lbs. I fit in pant size 12&14, depending if I want a tight or loose fit. This panty fits me in a L, even if I gained a couple pounds. (The No-Show Bikini fits better for me in an XL). I like this Leakproof Cotton bikini for the colder winter months, I work outside in the construction business and have occasional leakage, mostly minor. I can be confident that leakage will not require me to excuse myself from the job suddenly or cause embarrassment. I have 3 pairs of this panty and am happy to grab them from the drawer on colder winter mornings.

    I like how comfortable they are! My period isn’t too heavy so I can’t speak on that but they worked for me!

    Amazingly Comfortable

    These are my favorite of the three styles I purchased. I really like the cotton fabric. It's soft, fits well, and stays in place- no wedgies or leaks. They are great for light days or as a back up coverage if also using tampons.

    I've never been so happy with underwear

    I've been a Knix fan for many years, and swear by their leak proof undies. That said, I could not possibly be more impressed with these. They're incredibly comfortable, absorbent enough that I don't feel like I'm wearing a wet diaper all day, and really a lovely underwear experience. Thanks for the upgrade, Knix!
