In reply to j.anstee:
I'd actually totally disagree with Adam, I have been using The Jottnar Hymir and Belgamir jackets for the last two years for work and play, dry as a bone and the best performing jackets I have ever used. And I spend a lot of time in a waterproof jacket. I have had a blast with the Rab neoshell gear and thought it was very leaky. Previous to using Jottnar I was using an arc'tryx Alpha Sv as my bad weather hardshell and found it iced up inside in winter and leaked in summer, with the breathability of the Jottnar stuff this doesn't happen. I should point out that the Hymir and Asmund jackets are made of a lighter weight shell fabric that allow the wind to get through, making them amazing for high output activities, winter climbing, ski touring, running, biking ETC. but if you are going to be out in high winds for a long period choose your mid layer carefully.
It is also interesting to note that Jottnar pay very close attention to client feedback and since 2013 the belgamir shell has changed every winter season, for the better, some of my colleagues are using the latest version and it's incredible actually seeing a brand listen to its users.
