      How it works:

      Experience Underlux™ Technology

      Embrace the comfort and confidence that comes with Dear Kate's patented Underlux technology. Our period-proof underwear offers three layers of protection, turning your menstrual worries into a thing of the past while contributing to a sustainable, environmentally-friendly lifestyle.

      Layer 1: Soft, Wicking Fabric

      This layer sits closest to your skin, made from a micro polyester fiber blend that swiftly transports moisture away from your body. Designed to keep you dry and comfortable throughout the day, promoting hygiene and well-being.

      Layer 2: Absorption Powerhouse

      Works hand in hand with the first layer, absorbing and wicking away menstrual blood or any other discharges. Infused with a natural Silver Salt compound, this layer is anti-microbial, fighting off bacteria, odor and preventing infections, leaving you feeling fresh all day.

      Layer 3: Outer Barrier

      Designed to enhance performance and provide protection, this outermost layer acts as a shield between your body and your clothes. Its unique stain-releasing technology, coupled with the breathability of the fabric, makes it leak-resistant, ensuring that your confidence never waivers.

      How We Compare

      The future of menstrual care is liberating, eco-friendly, and ready to embrace - every day of your cycle.
