I bought this vintage bomber leather jacket recently, and I wanna know if it'll withstand rain and/or what to impregnate it with. Its definetly not normal grain leather, but its not anything like nubuck either. its kinda soft to the touch, one could confuse it for eco leather (like the seller lol, it was a daylight robbery). It slightly changes its sheen when swiping it one way or the other (look last picture for visual reference). If anybody needs further details let me know.
