80% Targhee Wool, 10% Tussah Silk, 10% Bamboo. Targhee wool fiber is approximately 3-5 inches in length with an average diameter of 22-25 microns. This wool has a high crimp, resulting in yarns with lots of elasticity and 'bounce'. The silk adds shine and strength to the yarn and the bamboo (which doesn't take the dye) adds a lightness to the hand of the fiber. This fiber blend yields textiles that are soft and cozy enough for everyday use.
