This auction is for a Vintage Flight Jacket.  I paid $600 for it in a specialty shop.  It is medium size and a bit big for Medium and a bit small for Large? I punched it shortly there after moved to San Diego so it did not get much use.  It was a little big for me also.  It is in excellent shape and you see the decotative print on the lining is "LIKE NEW".  The leather is also in great shape.  The jacket is heavy and is conversation piece. 

The underarm measurement is 23-1/2 inches.  The leather is thick so it is between 22-1/2 to 23.
