You have Resistance to Force and bludgeoning damage while you wear this armor. In addition you can add your dexterity boost to your AC even though its heavy armor! You also don't have disadvantage on stealth like on normal chain mail.

Made of interlocking metal rings, chain mail includes a layer of quilted fabric worn underneath the mail to prevent chafing and to cushion the impact of blows. The suit includes gauntlets.
