What Our Gearhead(R) Experts Are Saying: "The Mackinaw Cap is one of those classic pieces you end up wearing for decades. The wool is thick, warm, and naturally water-resistant, and the hidden flap is a lifesaver when the wind picks up. I love how you can tuck the flap away when you don't need it. It's one of the most versatile cold-weather caps I've owned." When winter closes in, we count on the Filson Mackinaw Cap to keep us warm, dry, and ready for whatever the day brings.
