Chest Armor in Destiny is the single most effective piece of Armor a Hunter, Warlock or Titan can wear. Besides protecting the player from damage, Chest Armor also grants bonuses to the players abilities. The bonuses impact the amount of ammo a player can carry with Primary or Special Weapons. The higher the quality of Chest Armor, the more bonuses it gets. The higher the level of the piece, the more Defense it provides.
