Filson - Field Jac-Shirt Reverse Sat.

Inspired by the original 1970s design, the Filson Jac-Shirt is a versatile layer that offers extra protection on cool days without the bulk of a full jacket. This modern version is made from sturdy 9.5 oz. cotton reverse sateen, a fabric that is rugged and abrasion-resistant on the outside while remaining smooth on the inside for easy layering.

It features a classic button-front closure, a spread collar and two chest pockets with button-flap closures to keep essentials secure. The adjustable cuffs and straight hem are designed for comfortable, untucked wear, making the Jac-Shirt a practical and timeless piece for transitional weather.
