BFL sheep have curly, fine, rather lustrous wool which is one of the softest of the UK clip. The fleeces are not very heavy, only weighing 1 to 3 kg (2.2 to 6.6 lb). They have no wool on the head or neck, although the pattern and shape of the wool is most like the Wensleydale, but having smaller, tighter curls.
Bluefaced Leicesters are recognisable through their Roman noses, which have a dark blue skin which can be seen through the white hair, hence the name. They are tangentially related to the original Leicester Longwool breed. BFL rams are put over hill sheep ewes to produce mules, which combine the prolificacy of the BFL with the hardiness and mothering ability of the hill sheep (- mules are the UK's most numerous sheep).
Fully grown Blueface rams can weigh up to 110 kg (240 lb) and ewes up to 89 kg (196 lb). At maturity and at the withers, rams are 90 cm (35 in) tall and ewes 85 cm (33 in) tall.[3]
