However, unliked Phase I armor, Phase II armor was not pressurized and so required an external respirator in low-oxygen environments. The Phase II helmet crest, for example, does not come to a point in the rear, and there is an upgraded breath filter and annunciator on the front.

In Phase I, extra features such as macrobinoculars and rangefinders required additional attachments. Notably, their helmets included a life-support system, a tracking device and a commlink. The armor was made out of thick, white plastoid. This was convenient and cost-efficient, because it allowed clone armor to be mass-produced, with each set containing the same basic features. Since the clones were all based on a single template, they all had the exact same height, weight and build. Because of this, they also used Jango’s Mandalorian armor suit as the basic design for the clones’ armor, which is where the base design of the Clone Trooper Phase I armor comes from.
