Rainproof Cap for Striders

It is an item like the saddle that can be equipped by the strider by right clicking it on him. The way it works is once equipped, the strider won't take damage while being exposed to rain. This would improve your strider experience in the overworld. It is kind of frustrating to peacefully go for a walk with your strider and then see it die because it started raining all of a sudden. I'm completely ok with striders not going in/on water though. Also, the cap should not cover much of it's face (because it's cute), and it should be expensive to craft (require netherite ingots)
