    So comfortable

    Soft, comfy, fabric, barely there feel. Light coverage is just perfect for those bothersome bladder leaks. The embarrassing ones that leak through to your slacks, jeans, etc.

    Way too small

    I fit comfortably into many different Knix styles in a size medium. Some mediums are even a bit roomy for me. However, these were completely different and very small. Inconsistent sizing

    Recommend but with a caveat

    Love the styling and the protection. However, when damp, it feels damp against the skin, unlike a pad that draws moisture away into a separate layer. Nonetheless, I recommend this product and would buy it again.

    So great!

    I love them, I won’t wear any other underwear. They are a little bit pricey, but they wash great and last forever.
