A number of years ago I had a North Face Nuptse jacket that was the warmest jacket I had ever owned. It served me well for a good number of years before it wore out. So effective was it that it even kept me warm in a stationery car with the engine off for over 3 hours while I was stuck in snow and bad weather due to an accident further up the road that needed to be cleared. At no point with it on did I feel cold. Bored and needing the toilet yes, but cold, no. After the extreme cold earlier this year and the possible threat of a repeat, I decided it was time to reinvest.
(In line with current blogging practice, I should point out that I am not being paid or receiving goods in kind by North Face to mention their product or brand).
