>>4178926I answered that other anon. In my opinion, the US N3B looks most like Yuu's but its entirely too warm for any practical use. More practical is a US M65 with this furry hood that buttons onto the collar but it doesn't quite look right with its large pockets. For her jacket you'd probably have a better time just looking for some jacket with the fur hood, an N3B is expensive and impractical for something like this unless you're Canadian.
Chi's jacket is a bit easier I think. The Belgian M64 has the pockets and the big full size hood a lot of milsurp lacks, favoring a collar. They are also really cheap and lightweight so you can actually wear it comfortably. My only problem with it is that the Belgians really thought that Velcro was the future and it uses Velcro for every possible fastener which I find annoying.
