Bomber jackets... in... space!
After playing with some other designs, I worked out this sketch to help me think about designing the pilot. After playing some WC1 again, I decided I really like the classic fighter pilot leather jacket look. It's also a callback to the WC3/4/academy brown flight suit
The leather jacket is a protective garment that goes over the spacesuit proper (with holes for the suit hardware) to save wear and tear on the suit body (the suit itself is a two-piece soft system) and to provide some additional external pockets. It can also be worn off duty over a standard coverall or t-shirt to create esprit de corps among the pilots.
