You know it appears more and more that the quality down bags are coming out with super duper waterproof shells and they weigh much less than synthetics and are ohhhhh so much more comfy. So my question is this, how many of us are just plain terrified (I know I am) to make the switch to a down bag because of all the what if's? I can say that to this day I have only climbed into a sleeping wet once time and it was much more so due to my perspiration (hiking back to the tent in the pouring rain and in a rush) but cant say that I have ever had to really get into a wet sleeping bag per say. Interested to hear your opinions on this topic. How many of you have either used or pondered the use of a down bag in the mountains? I had my hands on some of the Western Mountaineering down bags this past week and all I can say is Wow! They are super light and so darn comfy!
