Pt 2 - Basically want one in an A-2 pattern, no real price limit but if its ~$1000 or less thats ideal. This Sacai one is the biggest brainworms I have.
If you’re going for authentic both Aero Leather and Shangri La Heritage will be good choices for you. Shangri La uses Lambskin, so it’ll break in faster, Aero ist MTO and will give you more leather options.
Not sure I want 100% authentic, I don't love the pockets or the knit cuff on the body on the original pattern, but these are super good resources for good repos if I do go that route
If you don’t want to go authentic might as well check out the rest of Aeros selections, they have some good riffs on the A2 design as well, like I could see this being up your lane maybe https://www.aeroleatherclothing.com/mens/windward/mto082
