The Icelandic sheep, among the oldest and purest breeds of sheep, is a cousin of the Shetland and Finn. The fleece is dual coated, with a fine undercoat called thel and a longer, coarser outer coat called tog. The tog fiber (fiber we carry) with a spinning count of 56's-60's, micron of 35 and staple length of 6-8" is lustrous, strong, and water-resistant. Available in natural shades.
