What is a Jac-Shirt?
While some call them shirt-jacs, jacket-shirts or shirt-jackets, essentially a jac-shirt is a overshirt made from sturdy woven fabric. The front closure can use snaps or buttons, and the level of insulation can range from very little to being as warm as a coat.
Why Choose a Shirt-Jac?
Our jac-shirts offer unmatched versatility for use in cool to cold weather. Much more than simply a look or style, a jac-shirt can take the place of a jacket, can be worn as a warm, low-bulk layer under a rain shell, and is especially useful when moving back and forth between inside and outside. A midweight jac-shirt can be worn as an outer layer, or underneath a down vest when more core warmth is needed. Jac-shirts blur the line between shirts and jackets, and can be used as either, depending on the weather.
What are Filson Jac-Shirts Made From?
The original Filson Jac-Shirt is made with 18-oz. 100% wool and serves as a heavy shirt or a light jacket. Since its versatility has made it so popular over its 50 years of service, we’ve expanded our Jac-Shirts assortment to include designs made with several different materials including Mackinaw Wool, cotton canvas, waxed cotton and other hardy fabrics.
Our Mackinaw Wool and CPO Jac-Shirts are both made with heavy 24-oz. wool and are ideal choices for cold, wet weather. The Filson Fleece-Lined Jac-Shirt has a tough canvas shell that is ideal as durable workwear in cold, dry weather. A waxed-cotton jac-shirt is a great layer for use in wet or muddy conditions, while a jac-shirt with quilted insulation makes a great choice for cold, windy weather.
