I have an expensive (for me) 100 percent beaver felt hat I saved up for and cherish! I didn’t have it when I started bike commuting and got it while recovering from a serious injury. I wear it at work every day and now I am ready to go back to bike commuting to work, I need help in figuring out how to transport my hat. Wearing it is not an option - need to be wearing a helmet. Thanks for ideas.
