Last week on a overnite hike the morning temp was 6 degrees, about 10 colder than forecast. I wore synthetic T-shirt under Marmot Dri-clime windshirt, a thick but waistlength fleece for insulation. Unlined parka over all. Was quite comfy even when taking down the tent. Fleece liners inside mitten shells are the best for me w/thin glove liners for manipulating camera & fastex buckles.
