I am unimpressed with softshells. They are heavy and they provide only 80% protection. While that might be all that's needed for a three-season day trip or in-town wear, it's neither good nor light nor compact enough for my multi-day hikes. Until they come up with a 100% rainproof, windproof and true high breathability jacket that's as light and compact as my current shell and insulation jackets combined... I'll stick to the flexibility of two separate pieces:

Perfect hardshell -- eVENT with pit zips, stowaway adjustable hood, and hand pockets -- weighing 10 oz. or less. Or a Driducks with high tear strength.

Perfect insulation -- a synthetic jacket that approaches 800fp in weight and compactness for the same warmth.
