Most of malabrigo yarns are made with 100% Uruguayan Merino wool. Uruguay has one of the biggest wool supplies in the world, and a very, very good wool with regards to softness. Our wool is 100% produced by uruguayan farms that allow their sheep to go free-range through the hills and are herded by actual old-style shepherds. The controversial practice of mulesing does not exist in Uruguay. Some of our yarns use other fibers, such Silky Merino (a blend of our Merino and top-quality Silk), Mora (100% Mulberry Silk) and Silkpaca (Baby Alpaca from Perú and top-quality Silk). We always ensure that our materials come from the best suppliers we can find around the world.
