Jennifer,
Go with the soft shell.
I come from a background of winter backpacking and light mountaineering. Shoft shell cannot be beat. It is water resistant, windproof, breathable and comfortable. I have worn mine in every situation from a winter mountain bike ride to the a winter summit of Mt. Washington. I do not know much about a lot...but I do know about winter gear. Soft shell is worth every penny you pay for it.

Now shoft shell comes in different weights. You would want a light one for running. The one at Campmor looks great.

Let me know how you make out

ps...see me in my avatar? that is one of my ss jackets.....
