I bought my first 0-degree sleeping bag well over a decade ago now from The North Face and it has followed me all over the world, keeping me warm in a broken down van in Iceland, in northern Michigan when the temps outside were well below zero and in a camper in the Colorado mountains. In fact, I keep two of them in my trunk during the winter in case we break down in the mountains and need to stay warm.
This version is insulated with packable down and features an awesome retro color scheme.
