not only a moto & mil leather jacket nut but the G-1 is my fave. there are so many varieties of G-1 but the main division is those made for military use and those for civilian use. everything can be styled the same even, and there will be differences because of the use made for.
actual mil contract G-1s are historically cool, but quickly mass manufactured and you will find 'acceptable' contract faults. those who love the G-1 need at least one historical. BUT if you love them you also need a more well-crafted version, which would be a premium G-1 civilian version with actual mil contract design elements.
that would be this great G-1. albeit it does have a few differences: 1. made of more premium lambskin, 2. side entry hand warmers (which are expertly done so as to be hidden), 3. detachable mouton collar (mils are not detachable.
all of the additions of the civi version make it non-historical from a collector's POV, but more usable. Of all the many G-1s i've ever purchased, this is the most high end and enjoyable to luxuriate in. it was a real treat for myself. and yes, i knew it was made in China to Schott's design/production standards. it is such a wonderful jacket, that does not deter me from loving it.
