What is Momme? ⬇️⁠ ⁠ Momme is a unit of measurement and describes the silk weight and density. The thicker or heavier the silk, the more it drapes, the softer it feels and the longer it lasts. Slip® customers have remarked time and again how amazed they are by the difference in the feel of slipsilk™ compared to other suppliers’ products. All slip® products are made from pure mulberry silk with a thickness of 22 momme. Slip® pure silk pillowcases are the very best available - because we believe you deserve your 8 hours of uninterrupted beauty sleep. 🫶
