A silk pillowcase swaps cotton for smooth mulberry silk, and the main differences between brands are size, silk weight and how the case closes. We compared three mulberry silk pillowcases from Slip, Blissy and Brooklinen.
How We Chose
We picked three well-known bedding brands that sell a single silk pillowcase on Amazon. The sizes are not identical: Slip sells its pillowcase in a 20 x 30 inch queen size, which it calls international standard, while Blissy’s standard is 20 x 26 inches and Brooklinen’s standard is 20 x 27 inches. Slip and Blissy close with a hidden zipper and Brooklinen with an envelope flap. Brooklinen does not state a momme weight on its current page, and Slip does not list an OEKO-TEX certification. Specs come from each manufacturer’s own product and care pages. Each card lists the warranty or guarantee from the manufacturer’s own policy pages. Prices are the Amazon prices on the date shown.

Slip’s page lists its pure silk pillowcase in a 20 x 30 inch queen size, which it calls international standard, made from grade 6A long fiber mulberry silk at 22 momme with a charmeuse finish. This version closes with an invisible zipper.
