Originally I bought this jacket for a relative working in Finland for the year, but they'd already bought themselves another jacket.
So I ended up taking it on an expedition to the Kunlun Mountains in China, where the temperatures varied from -20C to +10C whilst we were there.
Obviously, a jacket of this calibre wasn't required when the temperatures were above zero.
The jacket was incredibly warm when the temperatures plummeted below zero. The hood was actually too warm at times, but at least I was able to wear a helmet with it. The fleece lined and elasticated cuffs prevented snow from building up inside the sleeves. The hand warmer pockets were a godsend during the strong winds as we approached the tops of the higher 5000 metre peaks. So as far as warmth was concerned, the jacket lived up to the job and I didn't get too cold (just my hands, but that was more down to gloves than the jacket).
There were plenty of pockets to store a few sweets, snacks, map, compass, etc. All of which had zips.
There were only a few small things that would cause problems over time. The velcro tabs would always catch on the draw strings on zips and on the internal mesh water bottle/flask holder. The velcro is slowly wearing away at them both. However, you could always replace the draw strings with 2mm cord, but once the mesh holder goes, it's gone for good, so take care when opening and closing the zips that nothing catches the velcro- sealed storm flaps.
Despite the minor problems, it's still an amazing jacket and well worth the money. 5 Stars.
