Western Mountaineering NorthLite Super

I love this bag! It is very light and compressible because of the light 1.2oz ripstop fabric and quality down but lofts up to a full 8" at the lowest point by the shins. It has an efficient narrow cut which is appreciated by skinnier to average folks (I'm 5'10" 145lb). It has loft and fill weight comparable to bags rated to -5 to -15 F while weighing in a lot less.

Excellent build quality and detailing including a huge neck collar and stiffener tape along the zipper that works really well. I favor a light nylon shell over Dryloft because it has much better breathability, holding in less water vapor.

(Of course, you also save weight, money, and have a more compressible bag .) For long trips, I would bring along a vapor barrier liner, a good idea for any down bag. Best of all, it's made in my hometown, San Jose.
