A 75/25 blend of Bluefaced Leicester and tussah silk.
Part of the English Longwool Family, the Bluefaced Leicester (pronounced "Lester") breed was developed in the early twentieth century. The fiber is fine, with a micron count of 24-28, silky, and lustrous. It’s fine enough to wear next to the skin and durable enough to wear well. Silk adds strength, softness, and shine.
