Gun crew question for large turrent/cannon ships

[MarkShot]

I know that this question is somewhat out of place relative to DW, but I thought this would be a place to get an answer.

I was watching the History Channel on the HMS Belfast. All the gun crews were wearing white hoods and white gloves. I have seen that before.

What exactly is this garb and what is its purpose?

Thanks.
