Sewn by artisans in our studio by the Bay, our masks are made with an exclusive 3-ply construction technique. A limelight blocking layer of breathable felt is sandwiched between a sumptuous layer of 16 momme, sueded silk and finished with a top layer of silk or wool. An unobtrusive, narrow band of stretch velvet keeps the slightly over-sized mask in place. “Why over-sized?” you may ask. After extensive testing we discovered the best size and shape to block out unwanted light and to keep in dreamy sleep.
