Cold weather can be a real killer for those under-prepared and who find themselves exposed to the elements in sub-zero temperatures.

Armed with a little knowledge and the right clothing/equipment, you can comfortably brave most cold weather conditions on the planet.

British Armed Forces routinely operate in -35C conditions in areas such as Norway and Estonia.

Here is my advice on how to keep warm during the winter snap this season:

First and foremost, it is all about preparation ... be prepared if you're expecting to find yourself in a cold weather situation.

Wear clothing in a layered system. Three layers in fact: the base layer, insulating layer and outer layer.

The base layer is designed to wick moisture away from the skin and to keep you dry. Merino wool is your best option.

Leggings and undergarments are not just for your grandparents - Merino wool really does work - so wear them.

Next layer on top is the insulating layer - a feather down jacket, or wool, is your best option as both help to trap warm air inside.

Then finally an outer layer - a Goretex waterproof jacket to keep out the water and wind is invaluable.
