The first thing to say, although it is repeated so often that it may seem a cliché, is that a jacket like this is a work of high level craftsmanship.
From an aesthetic point of view, perhaps it is a matter of taste: in the Schott catalogue the 582 is among the most essential ones, in terms of shape and with respect to the way in which the leather it is made of has been cut.
What matters a lot, however, is utility, because a garment like this should be worn because it is useful, rather than for fashion: I believe that in any circumstance - even in the height of summer - in which there is wind and parts of the body such as the head, neck, elbows and arms are exposed, this vest is an effective shield.
The fact that it is almost completely unlined except in the sleeves and on the shoulders and its weight - which is not light in the common sense of the term, but compared to what light is meant for leather garments - makes it suitable for intermediate seasons , including those summer days when, whether you are on a motorcycle, piloting a boat or driving a car with the windows completely open, you need something that provides more shelter than a fabric like cotton and doesn't make you sweat instantly like nylon .
The buttons on the cuffs allow you to decide whether to let air pass inside the sleeves or not: something that would not be possible in the case of a bomber jacket, with the cuffs and waist made of knit, which also has other advantages.
What else: perhaps the zipped pocket should be enlarged, even if only slightly (the A6 format of a small notepad and additional room for a pen), in any case it is large enough to contain a pair of sunglasses, if they are not the huge ones you sometimes see around; the front pockets are supposed to keep your hands warm, but they contain some small objects (keys, smartphone) without worrying about them slipping away: this is the case in which the front pockets like those of the bomber jacket make you realize what they are needed. On the other hand, it also depends on what else you have on: all you need is a shirt with a breast pocket, some chinos with large pockets and you have less need to fill your jacket with stuff.
As for the leather with which it is sewn, the impression is really strong in terms of the singularity of the color and the effect it has when touching it.
Regarding the size, the tool for help in choosing the right size contained on the Schott NYC website is precise, as long as you know how you want the jacket to fit; As soon as it comes out of the box it may seem stiff but just keep it on for a short time, for example while driving, and that feeling of stiffness will go away and the comfort will remain.
