ToolBoxXArmoredElytra

This plugin allows you to combine any chestplate with an elytra.

The result will be an armored elytra.
Armored elytras offer the same amount of protection as a any chestplate and they can have the same enchantments as well. This means that you can add protection, fire protection etc. to the armored elytra.

By default, you can only see the elytra when a player wears an armored elytra. However, you will be able to see both the armor and the elytra at the same time if you install THIS Fabric mod on the client
