Thank you for viewing! This is a Tomahawk Jumper nylon flight jacket. It has a design similar to B-6, CWU, and MA-1 jackets. It has a boa collar. This collar boa is removable. It's a slightly short length with pockets both inside and out, making it excellent in both design and functionality. Furthermore, it contains padding, so it's light and warm! Instant purchase and questions are welcome! Thank you for your consideration.
