Took the Atom on a short hike with a silk weight capilene base. Was in the high 20s and quite windy (windchill of 0 deg.). Atom is surprisingly warm. Borderline too warm if head down and moving up the hills. Comfortable when stopped and seems to breathe well. Surprised by wind resistance. Need to try it more but really impressed so far. With a Peleton 200 under it I think I could spot and stalk in quite cold conditions. Really curious to see how it feels with Kuiu super Down under it. May be able to glass in really cold windy conditions obviating the need for any additional insulation. Also, I got an Atom in the color ‘Basalt’. Real nice hunting color.
