Believe me, when you have to board a plane in your last set of clothes that you have worn for a week in the wilds, not only you but your fellow passengers will be very grateful that evolution created wool for us to wear.
In these pages you will find that I have a bias towards natural materials like wool that is based upon long experience. I do not dismiss synthetic materials as they definitely have a place and are often cheaper but price is not my first consideration when taking my body into the Arctic.
I need my clothing system to perform first time, last time and every time and so far natural materials have never let me down .
