Why Silk
The finest fiber on earth. Here's the case for it.
Mulberry silk is produced exclusively by the Bombyx mori silkworm, fed a diet of mulberry leaves alone. That singular diet produces the smoothest, most uniform, and most prized silk filament in the world — the standard against which every other silk is measured.
Glides, Doesn't Grip
Under a microscope, cotton is made of short, twisted fibers with a comparatively rough surface. Mulberry silk is a long, smooth continuous filament, so hair and skin glide across it instead of catching.
Natural Protein Fiber
Silk is built from natural proteins, chiefly fibroin. It's the reason silk feels cool, smooth and soft against the neck and face in a way plant fibers don't.
Reduced Friction
A smoother surface means less friction against your hair and skin every time you pull the hood up or turn your head, from morning to night.
Lightweight Luxury
At 22 momme, the lining is substantial enough to last and still light enough to disappear when you wear it. You notice the feel, not the weight.
Temperature Regulation
Silk is breathable and naturally insulating, which is why it has been worn in both warm and cold climates for thousands of years.
Durability
Despite its delicate feel, silk is one of the strongest natural fibers for its weight. Mulberry silk, from silkworms raised on mulberry leaves, is widely regarded as the finest grade of silk.
The Science, Simply
Why Mulberry silk outranks every other silk.
Not all silk is equal. Wild or "tussah" silks come from silkworms that feed on a mix of leaves, producing a coarser, less uniform filament. Mulberry silkworms eat only mulberry leaves under controlled conditions, producing the longest, smoothest, most consistent filament — graded by momme weight, with higher momme meaning denser, more durable silk. We use 22-momme, the grade favored for luxury bedding and now lining our hood.
Silk Weight Index
Higher momme = denser, more durable silk. 22-momme is the grade used in heirloom bedding — and now lining every Sovereign hood.
