    Better design; however could use improvement.

    This is an upgrade from their older version, but it absolutely needs to have the gusset run all the way from front to back. It does not provide adequate coverage while sleeping and while it offers full coverage in the rear for back sleepers, it does not offer any additional coverage in the front for side/front sleepers. Very disappointing.

    Not company's fault. Accidentally ordered. ULTRA,

    I did not like the feel with panel up the back. Previously ordered briefs. Like a 3. Wre so comfortable. Wish could be a bit less in cost.

    Get them!!!

    These are soooo comfortable, absorb tons, and just keep me feeling clean and confident. They also have a litttle more stretch than the lighter absorbing panties.

    Mom loves them

    My Mom loves Knix. She is able to wear with protection from leakage without all the bulk of depends. Her cloths look nicer and she is able to cross her legs.

    She feels more feminine.

    New style for me

    I love the feminine look of this style. Im a big fan of Knix but this was my first purchase of this style. I love it. My advise? Get adventurous and try something new.

    Not at all what I expected

    Feels like a diaper— not at all like period underwear purchased in the past. Didn’t realize I couldn’t return unopened merchandise. Will be donating.
