    Unfortunately flawed

    I love all my other Knix, but unfortunately this style the band on the top is so itchy and frays and gets sore over time. I would recommend against these, get a different style instead!

    Perfect except for the itchy waistband

    I absolutely love these for sleeping when I'm on my period, but the waistband is so itchy and scratchy. If they could update the waistband, these would be perfect.

    Favourites!

    I love these (please restock mediums!). I have other knix underwear and I like them but I find that the elastics dig in around the waist and thighs even when sizing up. These are sooooo comfortable and soft. I am typically a size small in pants but often go for a medium for underwear and bikini bottoms because they fit more comfortably. The medium is definitely a bit loose on me around the waist but I like them that way. These are the only thing I want to wear when I'm on my period and uncomfortable.

    Comfy and a worry free night!

    Just as the title says!

    Have asthma that makes me cough at night, I’ve borne three children and I’m over 65. ‘Nuff said!

    I love KNIX. All my underwears are KNIX. I also have dream shorts. But they did not meet the standard. I do not have long nails and when I was pulling my shorts up it teared through. Shorts are thin which is good for the heat but not good for out doors.

    Comfortable but not ideal for overnight coverage on heavy nights!

    Loved the fit and comfort of these but unfortunately I assumed they were absorbent enough for the first night of my period but they ended up leaking :( I would really appreciate if the products had their absorbency rating marked inside because I wasn’t able to get this information online under the product info page because it’s sold out.
