100% Pure Mulberry Silk vs. Polyester Satin
Many "satin" bonnets on the market are actually woven polyester, not silk. Polyester satin is thinner, traps heat, and creates more static and friction against hair — the opposite of what you want overnight. Silkora's 22 Momme, Grade 6A mulberry silk is a natural protein fiber that's naturally hypoallergenic, temperature-regulating, and far gentler on both hair cuticles and skin. Momme (mm) measures silk density — the higher the number, the more durable and effective the silk. At 22 Momme, Silkora sits in the luxury range used for premium pillowcases and sleep masks.
