The brim of the Akubra Sydney, AKA as Fedora by some vendors, like the rest of the hat, is constructed of a very soft pure fur felt that is so pliable that you'll never notice the headrest pushing it up. That's why it's my favorite driving hat.
With a 2 1/2-inch brim, 1-inch grosgrain ribbon hatband, and a moderately tapered crown, it's a classic fedora shape that comes with an open crown that can be dry-bashed into a pinch-front center crease in about five seconds. The soft felt and premium reeded roan leather sweatband makes it the most comfortable right-out-of-the-box hat you'll ever own. Available in charcoal and regency fawn at www.davidmorgan.com for $130 plus $8 shipping.
