Using a lint brush or the adhesive side of tape will remove dust and dirt on wool hats. If your wool hat gets out of shape, you can use steam from a tea kettle to reshape it. Hold the hat in the steam and allow it to soften. You can then reshape your hat to its original shape and then let it cool down before wearing. Always place a hat upside down on its crown if you do not have a hat rack for storage.
It's my go to hat now.
Glad you like it! Enjoy and be sun safe!
