One of a kind Filson ultra lightweight quick dry cap with unique Filson 1897 shield polar bear patch sewn on. Very flexible hat material best suited for quick dry or lightweight stow away use. Metal hat size adjuster on back with tuck in for excess strap material. No sweat stains in the cap minor scuffing on the back clasp. I measure my head at 23in and this fits very easily and can accommodate a pretty wide range of fits I assume. Hat volume is low fitting close to the head top. Custom patch has soft felt like feel with matching tan thread used by Filson store.
