Care

Machine wash with a wool program and use a wool detergent. Wool detergents retain wool's natural resistance to dirt and odors. However, you rarely need to wash wool—just air it out, and that'll usually do the trick.

The terry knit is fairly smooth on the outside and has loops on the inside to trap air and insulate better. The loops have limited tightness, so avoid using hook-and-loop stuff and other rough items against the jacket.

Wool also pills a bit, especially where your arms meet the sides. Pilling can be removed gently with a buzzing machine or carefully with a razor blade; just avoid damaging the thread of the knit itself.
