3.8

Knix earns strong reviews for leakproof underwear that reliably prevents leaks, feels soft and seamless, and comes in multiple styles and absorbencies, but opinions on bras are mixed to poor, with frequent complaints about support and fit. Reviews also flag sizing inconsistency, tight waistbands and less-breathable fabrics, occasional coverage issues, and some users find washing and integration into routines cumbersome—useful to know if deciding between period underwear and traditional options.

  • I have been wearing Knix for 5+ years now. For both period and non-period/sweat/athletic day-to-day, I feel like Knix just makes me feel at ease. The only drawback is sometimes the waist elastic is a little tight, so sizing up makes it more comfy in my opinion!

  • Such a fan of Knix bras! These bras are wireless, which is sooo good for your overall breast health and it makes them super light and comfortable to wear. Holds up the girls really well, with excellent supporting straps that are adjustable on some styles! Feels like I have nothing on throughout the day when I wear these!

  • I love these panties. I have both regular and period ones. I don’t love the boy short period panties because they’re a little bulky. I prefer the Thinx version. Still, all around, great underwear that is really comfortable. Was not impressed with their leggings.

    Feedback

    Less bulky boyshort period panties and better, higher quality leggings.

  • High five to Knix on the leakproof seamless underwear! Buttery soft, feels like a warm hug around my butt when I wear these, which is what I want during that time of the month. These have 0 VPLs and fit perfectly. Sometimes, I find with seamless stuff that the adhesive along the seams wears away after a few washes and the seams come apart... but not these! 1.5 years in and they still look new.

    Feedback

    I've also tried one of the cotton pairs. They fitted a little smaller so I would say size up. The cotton pair is also lovely and soft, but ultimately I didn't like them as much as the seamless pair b/c of the VPL.
