are there any mods that allow or add gauntlets/bracers to act as shields?
or are there any mods that have shields that look like bracers/gauntlets?

Because when I see my character(s) walking around with a big, bulky shield, it bothers my thought of "grace" and "finesse" for my nobler characters such as my Mage or my Noble.

Carnithus Armamentarium has, among other things, a gauntlet that works as a shield: it's actually a bracer scripted to add an invisible shield everytime you equip the gauntlet, giving the illusion that you're blocking with it.
It also has a bladed gauntlet that similarly adds an invisible weapon.

Carnithus mod is maybe a bit dated today, but still interesting. There may be other mods out that works the same, anyway.

can u give a link?
