Pelisse of the Light Brigade

Wondrous item, uncommon

This short fur-trimmed jacket is typically worn by elite cavalry units and helps them to shrug off missile fire and quick strokes of enemy sabers. While you wear it, you gain a +2 bonus to AC against ranged attacks, and there is a 50% chance that any ranged attack against you that gets a critical hit becomes a normal hit instead.

If you are controlling a mount and it is targeted by an attack, you may, as a reaction, make a Dexterity save (DC 10) to redirect the attack to you instead, giving your opponent disadvantage on the attack.

You can wear a pelisse of the light brigade over light armor, but not medium or heavy armor.
