Warm, even for human Popsicles. All the extra little stuff makes it an easy bag to live with. The mini pocket stashes my headlamp, the extra pocket in the footbox holds hot packs in place. And the draw cords are all shaped different so you don't need to be too awake to know which cord you're drawing.
Draw cords can get long when you cinch down tight. Not so long than they pose a choking hazard, but they may wrap around a pony tail and pull your hair. Shorten them up with some slip knots.
