I've never used a true soft shell. Like others, if find them heavy for the amount of warmth they provide. I do have a Kuiu Peloton 240, which I wouldn't consider a true soft shell, but I much prefer the Kutana hybrid. 40 grams of active insulation in chest and shoulders, fleece in the back area. It's nearly as light as fleece, warmer and more wind resistant than the 240, and it's cut snug and stretchy enough to easily go under a puffy. I'd like it even better if the collar were a couple inches taller.
