    Favorite underwear ever!!

    I first purchased Knix underwear about 5 years ago. I have tried other brands of leakproof underwear and I have not found anything comparable to Knix. The fit, the promice delivered and quality are the absolute best in my opinion.

    Super Leakproof

    These are comfortable and are great for leak protection. I use them for bladder leaks when I cough, sneeze or lift.

    Panties are great

    I have been a customer for many years and can verify the panties are durable and effective.. wish they identified the absorbency level along with size on the "label".

    Happy Knix user

    Love all these leakpoof underwear. From the speedy delivery, prompt exchange to the perfect fit and comfort of these products. I have high rise leakproof underwear, Cotton leakproof underwear and the boyshorts leakproof underwear. They are all perfect. I did order 1 size smaller which was my reason for an exchange.

    I have now ordered 2 styles of the Revolution Bra. Can't wait to get delivery.

    Thank you Knix for giving me a solution with the leakproof products.

    Perfect

    I bought my first Knix a couple years ago, and continue to purchase them. When I go searching for what I'll wear that day I always reach for the Knix pair. I know I am well protected from bladder leaks when I wear them. The panties are very comfortable, no bunching, no rolling, even after 100's of washings.
