    Wonderful fit-Looks Great While Protecting From Incontinence

    I am in cancer treatments and need extra protection from incontinence and GI issues. These Dream Shorts are very comfortable and give me peace of mind. I'd love to see these in the Ultra as well! Due to weight loss, I am rebuilding my underwear, but it is worth every penny! I've been wearing Knix for over 5 years!

    Dream Short

    I love the comfort of my dream shorts! I prefer that my behind is totally tucked in, and the dream short does this! Plus, I have the security of protection with the padded lining. It’s a winner for me!

    Absorbent strip too far back

    I love these and they generally work well, but I find the absorbent pad needs to be extended forward. Sometimes I sleep on my stomach while I'm on my period and it leaks everywhere! I am also really surprised and disappointed the dream short isn't offered in the highest absorbency, since that would be ideal for sleeping without worrying about leaks.

    Perfect overnight option

    These are very comfortable - very thin, not bulky. They are perfect for overnight. I would recommend

    Best for sleep and never had a leak

    These ultra period shorts are great for nite time. I can never get comfortable wearing a tampon and a pad because my period is so heavy . Since I’ve been wearing these I get the highest flow shorts and I’ve never had a leak. I wear them then wear some spandex shorts over them just to make sure they don’t move while I’m sleeping. Before these note shorts I would wake up and lbled through my ultra tampon and pad but now with these shorts I’m comfortable and don’t wake up to a bed that looks like a crime scene. Please don’t think I work for this company I’m being straight up with you, this product works I’m a customer for life

    Too bulky

    These are great for nights or days with heavy flow but the back is too bulky to wear with many of my clothes. If there was a lighter or medium flow option that was less padded, I’d buy several!
