This picture is wild!

Forgive me for not knowing all the parts that make up this particular piece of equipment, but damn ... First you have the Aragorn's standard black bracer underneath, that you can see in other pictures, so that's one layer. Then you slide Boromir's vambraces over that, which look to be three parts, the brown quilted pad, then the black layer, with the final brown layer on top, which looks to be stamped leather. And those top two layers are actually sewn together.
Those would be hard to make even as a 1:1 cosplay item, to do it in 1:6 is insane.
