The Filson Mackinaw Wool Packer Hat in Charcoal is a classic fedora-style hat crafted from 24-ounce 100% virgin Mackinaw Wool. This material is naturally moisture-wicking and insulates even when wet, making it ideal for various weather conditions. The hat features ventilating grommets for breathability, a 2-1/4-inch wide brim for protection, an interior cotton sweatband for added comfort, and a leather hatband that conceals the seam between the crown and brim.
