First you have to unlock the back of the hood, in order to fit the 2 "pins" of the hood in the 2 holes of the hood cover.
Then, well, it would be like a condom you would have to fit longitudinally, with feelling, meticulousness and a good sens of improvisation.
Personally, I've never used it, as I like the possibility to quick fit the hood in case of tropical rain. With the hood cover it's not so easy.
