That Cloudveil jacket, at 36 ounces, is overkill, in my opinion. My ID Dolomitti jacket (an outstanding jacket), at 24 ounces, is more than enough insulation for most conditions, and it takes a lot of room in the pack.
In fact, I just got a Patagonia Micro Puff Pullover,which weighs 12.5 ounces, that I'm looking to use to replace the Dolomitti for all but really cold conditions. At 2.6 ounces of Primaloft Delta insulation, it barely has just over half the insulation of the Dolomitti, but at half the weight and it compresses very small. If you get cold, as Denzel said in "Training Day," "man up"!
