Fetlock boot for young horses in techno sheepskin Save the sheep, the new line in techno sheepskin, is cruelty free. The lining is a man-made fabric, which is free from any animal derivatives. The techno sheepskin offers numerous advantages: it can be washed easily and dries quickly, while real lambskin requires considerable, lengthy maintenance; trapped sand comes out easily out of the loose, soft wide knit, minimising the risk of abrasions to the leg; it is more comfortable and a cosier fit than natural lambskin; it stays looking good for longer, while real lambskin tends to dry out, become stiff and turn yellow.
