    Never fails. Always comfortable. Highly recommend!

    I swear by Knix underwear during my period (high rise for overnight, thongs for daytime). The medium fits perfectly - not tight at all but hugs perfectly (and is not restrictive in any way - something I'm very sensitive about during my period!) For reference - I'm 5'4 and 127 lbs (and have a decent shaped booty ;)). On heavier days, I wear these with a diva cup. On my easier flow days, I can wear these alone with no issues.

    Happy customer

    These panties are very comfortable and reliable. I no longer need to wear pads so that’s a cost saver too. There’s no bulk even with the super padding. I am very pleased!

    Great Period Underwear!

    I love how these are truly no show and so comfortable! They are smoothing, and make me feel more confident when on my period.

    I don’t know whyI waited so long to try Knix underwear.

    These are all I’m going to wear moving forward.
