Familiarity: I've put it through the wringer
Love this thing. Bought with intended use being winter/spring ski camping and got the long for the extra space for drying gear (I'm ~6'). So much room in there; with liners at my feet the hood still completely covers my head, and I can roll from side to side without getting claustrophobic. This bag is comfy and toasty; coldest outside temps were around 10*F and I slept like a rock. Have woke with some serious condensation in the tent, the treated down still stays lofted and warm; dries quickly in the sun. The low weight is wonderful, too; same weight as the cheap summer bag I bought before this. Love the color, too; things don't get lost in the bright green.
I always look forward to a night spent in my Zissou, no matter where or when.
