Hi,

I wash my heavy wool clothes (pants, sweaters, socks, hats, mitts) in a heavy duty washing machine in cold water, gentle cycle, with Sportwash detergent. I then lay them flat over a rack to dry. I also do not wash them more than is needed, often light dirt can be brushed away instead of washing.

Occasionally I will shrink something (my DW is bad for this) but since I wear extra-large size and my son is a large, I just pass the item down to him.
