The Icelandic sheep produces a premium fleece.
The fleece is dual coated, with a fine, soft undercoat called thel and a longer, coarser outer coat called tog.
The tog fiber with a spinning count of 56-60 and a micron count of 27-30, grows to a length of 6-8" in six months.
It is lustrous, strong, water- and wear-resistant, and sheds off the rain and weather.
Thel is the soft downy undercoat, with a spinning count of 64-70 and a micron count of 19-22, growing to a length of 2-4".
The thel provides the loft for the outer coat and insulation for the sheep.
Tog grows from the primary hair follicles and the thel from the secondary follicles.
Tog is a true wool, and is not a kemp or guard hair.
The combination of the two fibers on the sheep gives superb protection from the cold and wet.
Icelandic fleeces are open and low in lanolin.
The weight loss when washed is significantly less than many other breeds.
