Army PTI Training Jacket
In the movie SkyFall, James Bond wears an Army physical training corps PTI training jacket with an SIS insignia under the left chest pocket. The jacket can be spotted in the teaser trailer during the interrogation scene and in the other trailers in the shooting range scene. It is not known which company made the jacket, or if it was made or adjusted by the costume designer. PTI Training Jackets are made for the Army Physical Training Corps. PTI stands for Physical Training Instructor.
Replica jackets are available at Joint Services Clothing, but several people had problems ordering from this webshop so be advised.
