Softshell and windproof don't really go together well, though many manufacturers sell them. Softshells are most efficiently used as an "action suit"...weather resistant enough to get through most conditions, while breathing far better than hard shells and drying fast. WindStopper and similar windproof laminates handicap softshell performance big time. Polartec Powershield and Powershield Pro are indeed excellent cold weather soft shell fabrics. The Ferrosi is very light weight, a great piece but not in the same class. I use Ferrosi pants for about May-Sept and they are great for that, same with the jacket. It dries insanely fast and breathes very well, but it really isn't very wind resistant. I pair it with a windshirt in the pack unless I'm just out for the day. If you keep up the DWR on a Winter Ferrosi it could be a useful piece, though to me it's kind of a tweener.
