Gaara's Sand Armor

The Sand Armor is a secondary defense jutsu unique to Gaara. Together with the automatic Sand Shield, it makes up Gaara's Ultimate Defense. The armor is employed by Gaara molding some of his sand over his body and hardening it into a shell that can protect him from harm should the Sand Shield be broken through. How much so is unclear, but given how much stronger and faster the Sand Shield has gotten in part 2, Gaara's Sand Armor has also undoubtedly greatly increased in power as well.
