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.

    Reviews Summary
    Customers say these bikini underwear are exceptionally comfortable and feel like wearing nothing. The soft, stretchy material provides a seamless, no-show appearance under clothing without visible panty lines. Many appreciate the variety of colors in the 5-pack and find them true to size, though some recommend sizing up if between sizes. Users note they may feel tight initially but stretch with wear. Common praise includes the seamless construction, durability through machine washing, and all-day comfort. Some concerns include sizing inconsistencies, waistband rolling, and visibility under certain clothing. Several mention these are their only preferred underwear brand, with many becoming repeat purchasers over multiple years.
