As far as i know, Ninja armor was light and only little (non bulky) as they need to be stealthy and move quick not encumbered by clanky armor as a samurai wouldve with a kabuto and shoulder pads and wotnot. Mebbe shinguards, elbow guards, a forehead guard/faceplate and basic plate armor for chest ( just light thin ones) and thats it. Sigh, Hasbro just didnt get it 
, oh well
