I've done the extremely wet thing
My Australian kit has been sorted for a decade or three
I know my kit is plenty good enough for -25 to -30C; it's that next 20 degrees I do not know about. What I have will cope but it's all about getting enough protection with minimum weight.
I can do it with a coonskin coat if I want to wear something that weighs close to 25 kilos.
I do need Antarctic rated clothing for Algonquin in winter
-40 during the day and -55 at night if a cold spell hits, that's almost Antarctic temperatures and no nice warm huts to retreat to either
I'd better start on the cold showers too very soon
