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.
Quality of material and manufacture are top notch.You simply cannot go wrong with a Conner Hat. As mentioned however, they seem to run a little large sizewise, but that is better than running small. Also this particular model has a somewhat wider brim for a fedora. Some like that, some don't. Also I notice Australian makers seem to go for a wider brim. Bottom line, I heartily recommend this hat.
