All Slouch style hats are knitted in sensationally soft easy-care yarn that is 100% machine washable and dryable. So no worries if you drop your new hat in the mud, just wash it!! Choose your favorite color and I will knit you a comfortable slouch hat in one of my many designs. Most hats average about 23 inches around but do stretch for larger heads. If you need a bigger or smaller size just leave your head measurement in the notes while ordering.
