    I liked the product for overnight.

    I used these for back-up overnight. They do feel bulkier than other styles so I personally wouldn’t choose to wear them out and about. But I am pleased.

    Best for stomach sleepers & postpartum!

    I got these for postpartum mainly! But fell in love with them for every period afterwards! I am a stomach sleeper, and would always get leaks from the front and these 360 coverage underwear have been a game changer! Highly recommend!

    Great product

    Love them but wish they were also available in other material like some of your other underwear. However, they do the job for me overnight, would love to hear you are considering making them in cotton !

    Too bulky and weird cut

    I regret trying these out, I don't like the cut compared to other knix high rise versions, bum coverage is odd - it feels like I'm halfway to a wedgie all the time. I also find the absorbent patch too bulky and uncomfortable.
