I'm an average size woman, and I have a big Agnes extra long so that hubby and I can zip our bags together (someday). For now, I often end up sharing with our 2 year old. The bag is roomy, but it is awfully cramped and I will end up either way down in the bag, or Little Man ends up way down in the bag. Of course, could be that my son is a crazy sleeper -- I've seen him in his own bed at night and he's all over the place.
