USAAF flight jackets
The USAC / USAAF used 3 types of materials for their flight jackets: shearling, leather and cotton. Most jackets were intended to be worn as a suit and so the nomenclature was quite obvious, for example B-3 flight jacket with A-3 flight pants, AN-J-4 flight jacket with AN-T-35 flight pants, B-15 jacket with A-11 pants, etc.
Nevertheless some jackets were issued to be worn on their own without a specific type of pants, this is the case with the A-1 and A-2 flight jackets. Some other type of US Army issue jackets were gladly worn by USAAF crew, for example M-1941 and M-1943 field jackets, tanker jacket, etc.
Some flyboys had their jacket decorated with squadron patches or even nose art painted. This was certainly the case with the A-2 jackets. These jackets were adorned by the crew and a way of expression. The jacket could be "upgraded" with patches and art work, mission score board, names, ... Every manufacturer had his own caracteristics and so the jackets are not exactly the same. They can vary in style, leather used, color, etc.
Underneath you'll see some military and civilian issue jackets worn by aircrew in the ETO and MTO.
Air Force issue flight jackets
Left: A shearling AN-J-4 (or AN-6553) winter flying jacket. The AN-J-4 jacket replaced the old B-3 jacket in 1943 and was the last shearling heavy winter suit used by the USAAF. This type of jacket was intended to be worn as a suit with the AN-T-35 (or AN-6554) trousers.
