If you plan on wearing that armor for long periods of time be sure to factor in ventilation for breathing and staying as cool as possible. It sound dumb to say but I know two guys at my old comic shop that built "home-brew" Mandalorian and Stortrooper armor and forgot to account for BREATHING in the damn helmets of all things! One passed out cold from lack of oxygen in the helmet and the other dropped from heat exhaustion where the armor and under padding trapped to much body heat. They solved the air flow problem in both the armor and the helmets by using cooling fans from old computers of all things. One rigged in the dome of the helmet pushed air down while a mesh fitting colored and shaped to match the armor allowed air in. One of the installed the fan on the back of his armor the other on the front of his armor, covering the opening in a similar manner as the helmet with the mesh. After one or two outings they even added vent tubes to allow air to flow through to the opposite [front or back] side from where the fan was. They used a combination of those batteries that you use to power large rc cars with and those big square batteries for a really big flashlight.
