Various Coverall Cags, aka also called Strom Cags in the US:
 
Ripstop Cag. Light weight, easy to pack vapor barrier with integrated spray deck.
Size Universal, which will fit a mid-sized person like me over my kit, including life jacket.
Size XL, for the larger sized paddler, think Jeff Atkins.
Comes in ink blue or mango yellow water proof rip stop fabric with gasketted wrists and pass thru pocket.
 
Warmer Coverall Cag, low fleece lined, made from. the same fabric as the spray deck. We call these people cookers. Put one on in the dead of winter and you'll be fixed right up. During the winter I often wear one of these over a paddlers suit and instead of a spray deck. All-in-one.
Comes in black, ink blue, or mango yellow. Hand warmer pocket lined in fleece is removable.
