Filson Jac-Shirt Designed for use as an outer layer, the Jac-Shirt is a shirt and jacket hybrid for keeping warm when the weather starts to get cold, but not too cold.


Sometimes, the weather is cold and you need a thick jacket to stay comfortable throughout the day. Other times, you just want an extra layer to add a little warmth without bogging you down with bulk. Those are the times when the Jac-Shirt will come in handy.

Made by Filson, it’s a strange hybrid of a wool shirt and a jacket. As in, they made it look like a collared, long-sleeved shirt, but with the weight of a thin wool jacket. Since it’s styled like a shirt, it carries an air of casual formality (which could make it acceptable at the office, depending on where you work), all while providing the extra warmth you need to be protected from rain, wind, and cold.


Designed for use as an outer layer, the Jac-Shirt is cut with a roomy fit, so you can layer it over shirts and vests when the temperature drops to slightly below mild conditions. It’s not awfully big, but it should wear over three layers of an undershirt, a dress shirt, and a vest just fine. A button-down front closure completes the shirt-like aesthetic, with two Western-style pockets on the chest adding an interesting touch. Those pockets, by the way, are fitted with hidden buttons to ensure they won’t snag into things whether you’re wearing it at work or in the outdoors. Construction is 18-oz. Seattle Wool.

The Filson Jac-Shirt is priced at $230.
