UPDATE 1.5
Ranger armors are still some of the coolest looking armors, and now they're made even cooler. The new 1.5 version of NDC includes rerigged shoulders, allowing much smoother deformations and eliminating most of the pesky little poke throughs that happen anytime you're in motion. All issues that plagued the previous version of the mod like the annoying see through holes in the armpits and back seams have also been patched out. Moreover, it includes a couple of fixes for some long standing problems, like the broken normal map that shows two invisible belts on the upper back of Riot Gear.

Info
Ranger armors are easily the coolest looking armors in the game, but are unfortunately made very uncool by the way the coats look, stiffly floating away from the legs. As explained by Josh Sawyer, they were intentionally shaped that way to avoid clipping in the original release, due to limitations of the engine at the time, not supporting cloth physics. Mods in the past have attempted to fix this problem, like Improved Duster Coats - YUP Edition, by moving the coats back closer to the body, which improved the look significantly. Natural Duster Coats takes this one step further by moving the coats even closer, touching the legs, and rerigging the coats to ensure natural looking movement and minimal clipping, outside of extreme poses and view angles. The following armors are modified:
NCR Combat Ranger Armor
Desert Ranger Armor
Riot Gear
Advanced Riot Gear
Elite Riot Gear
Courier Dusters- All variants


Requirements
Fallout New Vegas
Honest Hearts
Lonesome Road


Compatibility
The mod is built off of the meshes from Ranger armors and Riot Gear clipping weapons bug and posture fixed, which is included in the Yukichigai Unofficial Patch - YUP, so don't worry about overwriting the fixes. The mod should be compatible with just about anything, just make sure it doesn't get overwritten. It is fully compatible with ADAM Reborn, use Natural Duster Coats - ADAM and load it after ADAM.


Notes
The meshes in the mod have roughly 20% more vertexes than the original ones, which in the grand scheme of things, should have a near 0% effect on game performance. Another thing to note is the original riot gears used vertex coloring to darken some parts of the armor. You can see this clearly in the comparison screenshot with the riot gear, particularly the shoulderpads. Seeing that vertex color is just an overall tint here and just didn't look that good and killed a lot of the contrast in the original texture, I did not put back in the vertex coloring.
