Stay warm in any weather with Mackinaw Cap’s wool construction and hidden ear flaps
What Our Gearhead® 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. Made with Filson’s legendary Mackinaw Wool, this cap delivers natural insulation that stands up to wet, cold conditions without missing a beat. The quilted crown adds extra warmth, while the hidden wool flap pulls down to protect ears and the back of the neck when the wind picks up.
From early morning chores to late-season hunts, the Mackinaw Cap is built to handle it all with timeless style and rugged performance. Whether we’re in the field or around town, it’s the hat we grab first when the temperatures drop.
