How 22 momme mulberry silk actually works

Momme is just a weight measurement, the number of pounds a bolt of silk this size would weigh if you stacked a hundred yards of it. Blissy sits at 22 momme, which lands in a sweet spot: dense enough to hold its shape through washes, not so heavy it turns stiff. The 6A grade is about the fiber itself, long, unbroken strands pulled whole from the cocoon rather than the shorter, spun-together bits that make cheaper silk pill and snag. Long fibers lie flatter against each other, and that's the whole trick. A flat, tightly packed surface gives hair almost nothing to catch on, so instead of dragging against thousands of tiny cotton loops all night, it glides. Less drag means less breakage and less frizz to fix before coffee. The same smooth surface that stops hair from snagging also stops it from soaking up what your face puts out overnight, the oils and moisture your skin actually wants to keep. Cotton pulls that into the weave; silk lets it sit on your skin instead. That's the quiet mechanism behind the wake-up-dewier claim, and it holds up. The fiber breathes better than synthetic satin too, so it doesn't trap heat against your face the way a polyester copy would. The one practical detail worth knowing: it closes with a zipper rather than an envelope fold, which covers the pillow fully but is also the one part that has to survive being stuffed in a suitcase without snagging.
