Fabric Guide

Choosing the right Quality

Deepsilk™ offers a distinct combination of softness, skin hydration, and moisture retention, making it superior to many other bedding fabrics. While normal silk lacks the skin-enhancing benefits, Deepsilk is enriched with sericin, a natural silk protein that helps lock in moisture and protect the skin during sleep. This results in a fabric that not only feels luxurious but also supports skin hydration and elasticity, reducing overnight moisture loss.

When compared to cotton, linen, and bamboo, which are breathable and durable but can draw moisture away from the skin, Deepsilk provides a far more gentle experience. Cotton and linen, though comfortable, are absorbent fabrics that tend to dry out the skin. Bamboo is softer but doesn’t offer the same level of moisture retention or skin benefits as Deepsilk.

For those who prioritize sleep quality and skin care, Deepsilk is the clear choice. Its smooth texture helps promote restful sleep by reducing friction, and its ability to retain moisture supports your skin’s natural hydration. If you’re looking for bedding that combines exceptional comfort with real benefits for your skin, Deepsilk stands out as the best option.
