Purchased a NOS HockAy MA1 'Vintage' Flight Jacket by accident, had placed an order for another brand on-line & received the HockAy instead. I've had one of these before (last year), for me, IMHO the worst 'Vintage' reproduction (I use the word loosely) MA1 that I've encountered. The shell has a thin papery (cheapo) feel to it, can't imagine it taking much punishment. Shoulders, back length and sleeve measurements are about the same as a 'Vintage' series Alpha MA1. The chest is cut / sewn so that the slightest movement when zipped (on my frame) leads to the material instantly pulling taut and creasing. Zippers (Ideal) & knits are OK when compared to everything else about this jacket. One to give a miss IMO, this ones going back from whence it came.
