My Western Mountaineering HighLite weighs 17 ounces (tall size – the regular is an even pound). It’s down filled, and the zipper only goes halfway. With the stuff sack it is 19 ounces, but you could stuff it into a half-ounce bread bag instead. I have slept comfortably in it down to 25 degrees, but it is only rated to 40 I think. It has gone with me from Ecuador to Montana, and so far has held up better than it’s fragile look would suggest.
