    Great fit

    These had great absorbency without being bulky. I ordered several styles these were one of my favs. I had to exchange a couple pairs for a different size and the process was so easy!

    These are the best

    These are the best underwear! Love the fit and all the different colours. They are very smooth under clothing with no panty lines.

    Amazing as always Knix!

    I have purchased over 15 Knix products over two years and am always satisfied. The leakproof bikini is dependable, comfortable and easy to keep clean. Highly recommend this product and the leakproof shirts, which I recently purchased!
