An Adamantine Mantle is a cloak worn by Space Marines. They are cloaks made from threads of Adamantine, a tough and resistant material that can provide excellent protection for its wearer. The cloak often protects the wearer from high strength attacks, allowing the wearer to survive very heavy firepower which would normally fell any other warrior.[1][2]
