Is the newer "active insulation" like Polartec Alpha and the Patagonia Nano-Air type jackets really any better than a fleece plus breathable wind jacket like a BD Alpine Start? I've been trying to research this. As far as I can tell the active insulation dries slightly faster and is lighter, whereas the fleece plus windshirt is more durable in the long run. Can anyone that has experience with both be able to give their opinion?
