Unreal Lambskin is the industry"s premium synthetic fleece. It"s the ideal combination of durability and comfort. Why is Unreal Lambskin so popular? For 40 years this tough fleece has withstood the test of time, developed an extremely loyal following, and established itself as the industry"s most durable fleece on the market. Its thick pile gives pets a soft cushion to lie on. The lock-stitch backing keeps the material from unraveling or shedding.
