OK thanks for the answer! I was wondering because on the "Tech Specs" column it specifies [Shell] next to the breathability rating. So would the breathability of this coat with the liner be comparable to the Snowpatrol jacket which is single layer? And how about ventilation? I guess that it would be more efficient with the Snowpatrol since it probably opens through the insulation, unlike the Packer (unless there's a second zip in the liner)?
I'm having a hard time deciding between the two. As much as I know that layering is always a good idea to be able to adapt to climatic changes, I like the idea of wearing fewer layers than usual. I usually ride in quite cold conditions (like -4°F) and had to wear a nice warm base layer + a fleece jacket underneath my insulated Rossignol jacket to be comfortable. In very cold conditions I had to add another layer. But breathability is very important because I ride a lot of narrow backcountry trails, away from the wind, so it's easy to get really hot and sweat a lot.
With the Packer, if I start with two layers for the base coat and still have to add two other layers, I fear it might get too bulky. On the other hand, having a shell that's good enough to be used alone as a raincoat would be nice... but comfort and staying dry in cold snowboarding conditions is my priority...
The Snowpatrol looks like it might be warm enough to use only the base layer most of the time, which would be great for comfort. I suppose I could open the vents/use a lighter base layer when it's warmer outside and add the fleece when it's extremely cold. Could you estimate the kind of weather that's bearable wearing only a t-shirt with the Snowpatrol jacket? I wonder if it could really be too warm for my needs?
I need the expert's opinion on this!
Thanks in advance!
