Malabrigo yarn is a high-quality yarn from South America. 

From Malabrigo:

"One of our classics! We took our Merino Worsted, fattened it up, and plied it to create this squooshy treat of a yarn! Chunky’s nice smooth texture and semi-solid colors make it perfect for bulky cables and bold textures - or choose a variegated colorway and let the colors do the work! "

 

The squishyness and warmth of this wool is incredible and one of my favorite ever yarns to work with, I get them in limited amounts, and because it's very popular often tricky to re-order!
