There are many shells and alll seem very close in comparison, would you consider the Jovian to be the top of the line. How should the fit be in a layered system as the outer layer or under a say sub Zero, none of the sites actually cover the fit for those of us novice climber in the 5000-7000m rage
The Jovian is top of the line for certain. It's light and high tech. Breaths really well and sheds any precip. The fit is very form fitting. I would go bigger than normal if you want to layer much. It would be really hard to fit a sub zero underneath, but really you can just wear a sub zero over the top. If it's that cold it will be snowing not raining.
