How to wash

Knix underwear is 100% reusable and machine washable, just like your regular undies. 

  • Rinse

    • Not required. But for best results, you can rinse your leakproof with cold water in the tub or sink before washing.

  • Wash

    • Machine wash on a cold, gentle cycle with mild detergent.

  • Dry

    • For their longest life, air drying is best. Hang or lay flat to dry.

  • Avoid

    • Fabric softeners, bleach, ironing, or heat from the dryer.

      Love!

      These are keepers. Love the high rise under high rise pants and going into the spring/summer dress season. Baby blue colour is pretty. Knix doesn’t disappoint .

      Game Changer

      These are a game changer. I am postpartum and have been having leakage for as long as I can remember. I love not having to worry about needing a pad or a liner! I don't think I'll go back to regular underwear ever again!

      Alas, I can sneeze with impunity once again!

      The title says it all. I actually bought these in anticipation of our upcoming allergy season. I’m both too young, and too old for panty liners – lol! These are the perfect solution. And I’m astounded that the gusset feels as natural as it does. These get all the stars. Knix nails it again

      Leakproof and comfortable!

      The underwear felt very good on my skin. It's so nice that they are leakproof but not thick or bulky. Overall, very comfortable to wear.

      The fabric is strange, but I got used to it quickly. Overall, these are comfortable and provide good coverage. I think the high waist also helps my cramps a bit!
