I bought the Extreme Jacket as an absolute no brainer, like-for-like replacement for my trusted old one, which took a battering in the hills for over 20 years. Finally I had ripped the shell, forcing me to replace it. When I was introduced to Montane Extreme jackets as a concept, compared to layering up, I was skeptical to say the least. But six days camping in the Scottish highlands in full winter condition (-20s) blew away my doubts forever. Since that point I've encouraged many others to buy Montane. The new jacket is actually improved in many small details that make a difference - for example the fleece quality is improved, the pockets are deeper, and the zip functionality and jacket closure is a big leap. No doubt I will hammer away with confidence for another 20 years, well into my 70's!
