Fits great but useless for leaks

These panties fit wonderfully and are very comfortable but the leak proof material inside is so small that they immediately leaked. The pad is too far back.

Bladder Leaks

Game changer

Having kids, cancer, a sleep disorder and more has taken a toll on my body. I have over-active bladder with urge incontinence. I occasionally have trouble getting to the bathroom quickly enough and may have a small leak. Pantie liners do not control odor and a daily incontinence pad, for something that may not even happen, is expensive. Knix gives me the confidence to get through my busy day without feeling frantic about getting to the restroom. Of note, I was concerned Knix may be too small. I wear a US woman's 24 pant or 3X. I bought the XXLarge Knix and they fit beautifully.
