    Different prints feel different

    Love these a lot. I do notice that the leopard print panties fit differently. They feel tighter at the waist-slightly uncomfortable. The other prints and solids feel great.

    I tried the bikini in large and felt they were too tight. Tried the high rise in XL and now I feel they are too loose.

    Absolutely the BEST!!

    I have switched all of my underwear to Knix. I love the styles and appreciate the discrete protection. It’s such a great feeling not to worry about embarrassing leaks or wearing pads. I’m pretty young and these options blend in with “regular“ undies. Thanks Knix!

    No Show

    I wear these Knix when I don’t want panty and waistlines to show to show….and they don’t!

    I have asthma that leaves me coughing unexpectedly and hard. With my Knix I don’t have to leave the party!

    Perfect period underwear

    I’ve tried many brands over the years and always unhappy with the fit. These really work for me and I wouldn’t have even tried them if I didn’t live near a store and was able to test them out. I thought I wanted more cotton based period undies but turns out the comfort of these is beyond perfect and that is more important.
