The Active Jac has been a favorite on American ranches, farms, and factory floors since its release in the '70s. Built to move, this modern version is designed with stretch panels across the back and elbows. It's cut from warm fleece-lined duck that feels broken-in from the start. Previously known as the Full Swing(R) Armstrong Active Jacket. Full Swing was developed with insight from our Carhartt Crew, a group of hardworking folks who wear our gear on the job day in and day out and let us know what they really think.
