Blissful sleeping bag
This is a fantastic product. I bought it as a light weight summer bag and it will do that very well. I have been using the same sleeping bag for the past 20 years, a 20deg down Western Mountaineering bag that weighs just over 2lb. I have watched the slow development of sleeping bags through those 20 years but never saw anything that motivated me to upgrade. Some tweaks in the shape, replacement of the bottom with a pocket for a sleeping pad but no significant decrease in weight. Western Mountaineering still sells 20deg bags but they are only a few ounces lighter than my current bag. Not until I came across Enlightened Equipment. This bag is less than half the weight of my current sleeping bag and packs considerably smaller. Enough of a difference to make it worth spending money on new equipment. 40 deg is a great temperature rating for a summer bag. I'll mostly use this on kayaking trips in the Pacific Northwest. The shape is very functional. I've come to like using my bag as a quilt. This lets me comfortably move about and stretch out. As it gets colder the the foot box can be closed up and the bag connected to the pad for warmth. I can also undo the footbox and us this as a flat quilt. This will make a nice extra warm layer in a two person sleeping system that I have. Finally, the price is very reasonable. I call this product "blissful" because it lead to some very blissful nights of sleep. It is like a puff of air that keeps me warm.
