Packing Chaos

The week before an extended trip is always fraught with packing chaos.
What to take, what to travel with etc. Made even more complex because
our trip is to the other side of the world In a land of ice and snow.
Will come after just emerging from a Spanish summer!

We have 23kg hold luggage, 8kg cabin luggage together with a 3kg
personal bag. How on earth is all this mountain gear going to fit
in?
