    Soft, comfortable and gets the job done!

    I’m so glad I went with these. They are so soft and comfortable and the absorbency is excellent. I like that they go all the way up the front and back. Not only is this better for sleeping, but it just looks better as well. I’m definitely ordering more.

    EVEN BETTER!!!

    I have been a huge fan and almost daily wearer of the Super Leakproof Dream Short since they were introduced. I have also been asking (begging) Knix to make the protection from waistband to waistband. Well... they finally did that, and I couldn't be HAPPIER!!! These panties are so good... so good! The protection is great and the comfort is just fantastic. Easily the best panties I've ever had, ever.

    I love these, I would buy multiples. The fit is so good that they don't feel like too much to even wear under pants in the day time. They are also so comfortable for night time wear.

    This is my absolute overnight favourite leakproof underwear. It is really comfortable but also feels so secure. It just stays in place so well throughout the night. I would fill my drawer with these.

    I bought some in store, to try and I really liked them so I ordered another 6. The only thing is they are different with a full panel. They are still good but I like the ones I bought in store better. Hence the 4 stars. Still a great product.

    Excellent coverage!

    No worries when travelling! Excellent coverage!

    Not bulky, very good fit.

    Rolls a bit on me at waist, hence 4 out of 5, however, that will not deter me from buying more.
