The hood is a big part of the reason I'm using a Sitka Heavyweight Hoodie as my midlayer instead of the Kuiu Peloton 240. I have a hoodless 240 on the way and can see myself using it in combination with the Heavyweight Hoodie in some situations (whitetail hunting anyway). I'm interested in the Ambient and watching the thread on it closely, but I'm a little concerned that it won't be much warmer, if at all, than the Heavyweight Hoodie. If that's the case, I'll skip it because of how great the hood and scuba neck are on the Heavyweight Hoodie (love not needing to bring a neck gaiter with that thing).
