The Welsh Mountain sheep is usually white with a white face with no wool on forehead or cheeks and white legs with no wool below the joint. Females are polled but rams usually have curved horns, although some are polled. The fleece is thick and moderately long and the tails are not normally docked.
 
The fleece is strong and bulky and may contain coarser coloured
 fibres - red, grey or black and kemp.   These coarser hairs will not take dye but the rest of the fleece takes dye well. The staple length is between 2 and 4 inches and has a micron diameter of between 25 and 40 microns. It needs to be spun gently.
