If you're interested in accuracy...

At least on the East Coast of Canada (and my father fishes for a living, and I've spent time on the water) practically no one wears those hats any more.  Standard is baseball cap in nice weather.  In bad weather, all the jackets come with hoods.   And you wear the baseball cap.

The overall is pretty good.  And, the way they are shown is correct.  You wear them over the boots.

As for the survival suit, it needs a flap that wraps across the lower part of the face (when everything is buttoned up tight).  Colours bright orange or red.  Gloves are part of the suit.  Also needs reflective strips, epaulettes on the shoulders (used for grabbing the person), and assorted pockets.
