I have used the Jetstream for over two years on a number of hunts. I can't say enough good about it. It is warmer than it should be. With weather in the teens, I layer underneath, a couple polypro long sleeve shirts (using Kryptek now), then a fleece vest under the Jetstream. I carry a Sitka puffy in my pack if I'm going to sit awhile, as well as Dewpoint rain suit. The hood is a great feature also, especially in the wind.
I strongly recommend the Jetstream. Be sure to size it right; I usually wear a large, and the extra large hits me just right.
Which puffy are you using ? Kelvin Lite or Kelvin Down?
