Does anyone have any experience with the Tanker Jacket made by Cockpit? do they run large or small? I am a big guy and would like to do a tribute jacket for my grandfather's unit on this recent 75th Anniversary of the Liberation of Rome and his participation. He was a truck driver and heavy machinery operator in an Army Air Forces that was strafed wonded transporting supplies to Monte Casino and then was sent on detached service to an armor unit where drove a tank during the push to Rome. He was wounded a second time when his tank was hit by German artillery when he and the tank crew were sleeping under the tank. The men on either side of his both died but shielded him from some of the blast. My grandmother had a photo of him in a tanker jacket with his AAF unit insignia. Alas, the photo is in the hands of another family member and I no longer have access to it. Any input is greatly appreciated.
