Does Merino Wool Shrink in the Dryer and in the Washer

Merino wool is a popular choice for activewear because of its moisture-wicking properties and natural odor resistance. It’s also an excellent choice for baby clothing because it’s so soft against even the most sensitive skin. 

Wool fibers have natural crimps that make them springy, which means your merino garments will be less likely to lose their shape with time. This makes merino wool ideal for sweaters and other garments that you want to wear year after year with minimal pilling or wear.
