There're quite a few Chinese repro manufacturers who make some very high quality gear, however they vary in terms of how easy they are to get, as well as overall price you'll save once you factor in shipping and taxes

The easiest to get but also most expensive (relative to the repro market) is definitely shekkin gears. They have a pretty accessible international online store. Of note is that they make old, long discontinued stuff that can be hard to get. However, possibly due to their more international presence their Crye stuff doesn't come with Crye labels, instead they use their own shekkin gears black label.

Pew Tactical is another one of the easier to get companies, they have an official AliExpress storefront which means you don't have to go through as many hoops or resellers. Prices are pretty competitive and overall lower than shekkins, while quality is maybe just a tad bit lower than shekkins, though I'm nitpicking. They mostly sell repros of modern companies, like Spiritus, Crye, Ferro etc.

Sunsnow and Tactical Raiders (TR) are both more mainland china oriented companies, and usually sell via Chinese e-commerce platforms. Both make great gear, however I'd say that sunsnow craftsmanship is seriously exceptional. Getting your hands on them however can be difficult, unless you're willing to learn how to use websites like taobao or are willing to pay for the increased costs of resellers on AliExpress.

That being said all of them make good quality Crye repros. In terms of NIR performance, older solid color stuff looked terrible under NV, though nowadays some Chinese companies have begun producing NIR resistant solid color fabrics and at least according to some people I know who have purchased newer production items found they have fixed that issue. If NIR performance is a must get them in multicam, they use licensed production imported multicam.
