Highlands wool is specially selected fine long fibre, strong fine 19.5 micron merino fleece wool from the WoolConnect group of farmers in New South Wales.
It has a 98% comfort factor which means it will not prickle or itch sensitive skin. It will not shrink. The long fibres mean it wears well.
Wool is particularly good in cold weather because its insulating effect keeps you warm. It has much higher moisture absorbency than synthetics so it is always more comfortable than synthetic socks. Link to WoolConnect Website http://www.woolconnect.com/
