    Works well

    I have been going to another company for my underwear for incontinence. Knox was having a great sale so thought I would try. Material is completely different and kind of unusual to get used to but once I got the correct size, they are bad. Works for they are needed for.

    I love this brand and I swear by their undies! I have a light flow, so these are perfect for my periods. I dont recommend if you have a heavy flow, but they are great for what they are meant for!

    Comfy

    Comfy…sorta odd fit though.. Should they fit above or below hip bone?? Kinda shift while wearing from back to front which I’m fairly certain is non hygienic. Not really wearing due to fit.

    Fit Different

    I have what I thought was this exact style but unfortunately these ones are different and they don’t actually fit the same at all. Disappointed. Too much material that they roll up in the crotch part making them very uncomfortable.

    The idea is in the right place

    I think the V area is very thin. Therefore, I have had a bit of spillage. I would also suggest buying a size up. I purchased a large and I find it’s quite tight.

    Perfect

    These are so comfortable, I can’t tell I have them on. Relief knowing that I’m protected in case of a daytime “leak” when I laugh! Would highly recommend and will be buying more

    Fit Good

    I really like these underwear. The overall fit is good and they stay in place all day. The leakage protection is wonderful and I can feel confident all day. I will be buying more of these.
