If you wear your beanie frequently, chances are it has accumulated some sweat and dirt. However, washing our Lift Down beanie is super easy: just throw it in the machine with the rest of your clothes.
If you stain your beanie, you can just wash it using lukewarm water mixed with 1 tsp of laundry detergent. Once the stain is removed, let the beanie dry by hanging or by rolling in a towel. Do not iron.
