Reviews Summary
Customers say these French cut underwear are extremely comfortable and feel soft and silky against the skin. Many appreciate the generous leg openings and no-show design that doesn't create visible lines under clothing. Users frequently mention excellent absorption for light to moderate leakage, with many preferring them over traditional pads. The fabric is described as buttery and lightweight, with customers noting they barely feel like wearing anything. While most praise the fit and comfort, some mention the liner can feel slightly stiff, and a few note concerns about the absorbent area not extending far enough in the front. Common feedback includes easy washing and durability.

    best extended gusset

    The new and improved version with the extended 2" gusset is a game changer. I purchased Knix years ago for my bladder leaks but was just not completely satisfied with them because I felt the gusset area was too short in the front for my body. I would have accidents half on and half off the gusset. When I saw you made a 2" extension of the gusset I wanted to give them a try. And I am so happy I did. I love this version and feel extremely confident. They are very comfortable and do not rid up also. I am so happy with my purchase.

    So comfy and cute

    I’ve used period panties for a few years now and lemme just say this pair is by far my favorite. I hate having a panty line so I love that this pair gives me ultimate leak protection with a seamless line. I definitely will be purchasing more pairs.

    Love, love, love my knix!

    I'm sort of a clean freak. These panties make me feel clean and fresh. I don't have to worry about leaks with sneezes...(that's why I bought them! Allergies!) I'm sure I don't need to explain.

    The high cut is super comfortable. I also love the feel of the material. So smooth and silky.

    I wear a lot of yoga pants. The Knix don't show through. What's not to like?

    The only thing I'm upset about is that I didn't find them sooner!
