I also use a two piece Penn flotation suit and because I assumed ( incorrectly ! )that most of the family would want to go out in winter I have three suits, handy for crew who dont have flotation suits.
In winter the flotation aspect of the suit and the design to prevent circulation of water through the garment ( rubber on ends of sleeves ) are a definite plus, since survival times are short in cold seas.
I also have a skiing jacket I bough th in the sales, which is great for keeping warm - windproof/waterproof but would be next to useless if I fell in.
PS: No hot sea to drink on Neo ( thank god )
