I really liked the bear armor in the concept art, but was pretty disappointed to find that it's not actually in the final game. This mod replaces the neck scarf with one of two fur mantles. The first is taken from the Pellar's outfit, and runs down Geralt's back, but it hangs nicely and its my fave of the two. The second is taken from Skellige women's outfits.

Both have some issues with clipping, but editing the files at all causes a great deal of issues when it comes to the fur effect, and the weights in the mesh. Its barely noticeable, but if that might bug you, heads up.

This is compatible with the Mastercrafted Ursine Concept Art mod, and I presume the Concept Art Bear Armour mod. Just make sure to set them as a higher priority, so that this mod replaces the scarf from both properly. If either of the mod authors want to merge my mod with theirs, they are free to do so. Just credit me brah.

P.S.
Some people are asking me how I did this! Here's how!

So it was really a matter of importing/cooking the file without extracting the .fbx file.

So you take the file you want to be on the armour (Lets call this Fur.w2mesh). Look for the item you will be replacing (You have to replace something, far as I can tell. If you just edit the mesh, the fbx, you'll lose alpha information or weights and stuff. Lets call this item Neck).

take fur.w2mesh, rename it so it's the same name as Neck.w2mesh. Place your newly renamed fur.w2mesh in a file hierarchy that matches the original Neck.w2mesh (so if neck.w2mesh was in characters/butts, put fur.w2mesh in character/butts). Then cook, cache, pack and build meta that.
The real key is at no point should you extract or edit the w2mesh.

My specific files were, for the black fur, i_05_wa__skellige_villager and for the other one, i_01_ma__guslar. just search your uncooked files for those and you should be set. You could in theory replace this with whatever too, but the height maps are gonna be your worst enemy here.
