'Softshells' actually run a wide spectrum of materials, construction, and features. There are shells like Patagonia's Dimension and Ready Mix that look just like tradiional hardshells (hood, cut to cover hips) but are made with breathable material, and there are ones that look (for lack of a better comparison) sort of like a track jacket, but still have a wide and conflicting range of features and materials - examples are Cloudveil's classic Serendipity, Mountain Hardwear's Alchemy, Arc'teryx's Sigma and Gamma models and countless more.
Some have windproof membranes which are warmer (and, duh, windproof) but inhibit the breathability, some have fleece linings of various thicknesses, some are cut trim and some roomy, some have hoods and some none, some have heavier fabric reinforcements on key wear areas, some are designed for mountaineering and some for area skiing...and so on and so forth. There are a lot of excellent softshells out there, but you have to know what you want to get good advice.
So it wold be helpful of the posters were to give a little info on where and how they ski, and what they're looking for in terms of features, and maybe a little info on the rest of their layering system. Because pretty soon, a number of people are likely to chime in on this thread stating that they like the softshell that they happen to own and that's what you should get, and the shells will be as different as day and night.
