    Not the same as the last ones I bought

    I loved the High Rise Leakproof panties I bought some months ago so when I saw them on sale, I bought a couple more pairs. However, they are not the same. The leakproof padding goes right up the back to the waist, which is fine, but they are cut much higher on the buttocks which is uncomfortable. The have been relegated to my 'reserve' pair.

    Lifer!

    I started wearing KNIX 3 years ago and they are the only underwear I’ll buy now! Love that I’m supporting a Canadian brand too!

    Just ok.

    I liked the coverage. A bit brief around where the leg connects.

    Ultra Lake proof

    It is a little stiffer and tighter around the waist, but I think it will get softer as I wear it and wash it.

    I finally got Knix for me!

    Ive purchased Knix for many of my friends and relatives and although they raved, I still hadn’t bought them for myself.

    Just recently, I finally got myself the underwear and wow! Best decision ever !

    They are so much better than I imagined. The fit, the comfort and the look is excellent.
