Human beings, nevertheless, like to move and check out. We leave our cosy houses for a couple of days to trek in the Scottish mountains, or for a couple of months to top Everest.

Without a doubt the very best product for warmth-to-weight ratio is ‘down’, the layer of great plumes closest to the body of numerous birds, consisting of ducks and geese. These are springy and produce clusters which form air pockets within and in between the plumes. As anybody with double glazing understands, air is an excellent thermal insulator. Heat is moved by particles hitting each other. In air, particles are expanded and do not clash often, so heat is moved gradually. In a down coat, the heat created by the body remains caught within.

However down has a significant drawback. If it gets damp, it clumps together and loses its thermal homes. It’s still quite beneficial if you are summiting Everest, where any rainfall falls as snow which is huge enough that it does not permeate the coat’s external layer. However on a drizzly day in the Peak District, down is practically worthless.
