A quick and straightforward model costume you might know from the Metal Gear Solid series as Naked Snake's attire, flight trousers. It was a quick modification of a model by JGHolt that I have fit to the Rexouium Avatar base by RezilloRyker (Avatar not included). Its made with 1.5 Rex version in mind.

Credits: Model made by JGHolt originally.
