Zilk pillowcases, eyemasks and scrunchies are infused with silver ions, providing antibacterial and antifungal properties that keep your pillow fresher and your skin clearer. In addition, we use the highest quality silk available on the market today, 6A 100% mulberry silk, at 25 mommes (measure of density and durability).

Silver ions disrupt the biological functions of bacteria and fungi, effectively reducing their presence by 99.7%, ensuring a cleaner sleeping surface.

Yes, our 100% Mulberry silk fabric is naturally hypoallergenic, ideal for sensitive skin, and enhanced with silver ions for additional antimicrobial protection.

Absolutely. By minimizing bacterial and fungal growth, our products create a cleaner environment that can reduce acne breakouts.

Zilk products are easy to care for: simply machine wash on a cold, gentle cycle and air dry to maintain their luxurious feel and antibacterial properties.

We recommend washing your pillowcase weekly to maintain its freshness and effectiveness, though its antibacterial properties allow for longer intervals than traditional products.

For the longevity of the silk and silver ions, air drying is recommended. If necessary, use a low heat setting on your dryer.

The silver ions are designed to last the lifetime of the product (~2 years), ensuring long-term antibacterial and antifungal protection. The silver ions (single molecule of silver element) are bonded to the silk fibers during production. After 18 months, our research does show a small reduction in the silver’s antibacterial properties.

Yes, Zilk is fully committed to sustainability. Silk production has a lower environmental impact than cotton, using significantly less water and land and producing fewer carbon emissions. Silk is also a fully biodegradable fiber, and silver is a naturally occurring, non-toxic element. Our practices aim to minimize waste and ensure a responsible supply chain. In addition, our factory is inspected and certified by SGS to ensure fair labor practices.

No, Zilk products are cruelty-free. We do not conduct animal testing for any of our silk products or other products.

OEKO-Tex certification means our silk has been tested and certified free of harmful chemicals, ensuring safety for both your skin and the environment. It represents our commitment to high product safety standards.

Silver ions are embedded into the silk through a safe, environmentally friendly process that ensures they are evenly distributed throughout the fabric, enhancing its antibacterial properties. Our factory has passed inspections from SGS, certifying the quality and effectiveness of the silver ion treatment.

Silver ions interfere with the essential functions of bacteria and mold cells, effectively inhibiting their ability to multiply. This natural antimicrobial action makes silver ideal for embedding in textiles like silk.

'Momme' is a unit of weight used to measure the density of silk. Higher momme indicates a heavier, more luxurious silk, offering greater durability and a richer feel. Most of our competitors offer between 19-23 mommes, which reduces cost but also impacts the quality, durability, and feel of their products. At 25 mommes, Zilk is best-in-class to provide you with the most pampering sleep experience possible.

With proper care, Zilk products can last several years. The durability of silk, combined with the antimicrobial properties of silver ions, ensures a long-lasting product. However, for an optimal experience and most effective antibacterial properties, we recommend replacing your pillowcase after 2 years (assuming regular use).
