Dragon scale mail (commonly abbreviated to DSM) is the strongest single piece of body armor available. Its base AC reduction is 9, it weighs only 40, provides a useful extrinsic, is inherently erodeproof, and doesn't hinder spellcasting. It does not however provide any magic cancellation, and should hence be complemented by a high MC cloak. Dragon scales are body armor that might be dropped by a dragon. They have a base AC reduction of only 3, but are otherwise identical to the dragon scale mail of the same color. They can be converted into dragon scale mail.
