Filson Jac-Shirts have proven to be the most versatile piece of outdoor clothing for half a century. With the simple ease of a button-up shirt and the weather protection of 100% wool, it’s the layer you’ll reach for first when temperatures drop.

Sewn in our Washington factory, this jac-shirt’s wool provides natural comfort in a wider range of weather conditions than any other fabric. The 15-oz. fabric is crafted with a tight weave that delivers an optimal balance of breathability and wind resistance, along with the durability to last for decades. With its ability to wick moisture for evaporation and insulate when wet, wool has been the fabric of choice in the outdoors for centuries. Wool does not retain odors, making it simple to care for.

The pocket flaps feature hidden buttons that prevent snagging and provide a clean look. The hem is straight. Side-entry pockets on the lower side seams can keep hands warm or stow quick-access items. Our classic Jac-Shirt has earned favored status since the 1970s.
