Freezer? Don't say that word! Actually they are one of the few breeds whose fleece demands a high enough price for them to be profitable after they are too old to lamb. The fleece is oily and slippery,so tends not to tangle as easily as you'd imagine. The oil gives it weight too which helps keep it from matting as it hangs down and swings when the sheep runs. A bit like a spaniels flapping ears. Lol.
