I have had my -30 Cloud for over 20 years. The newer Clouds have a larger foot, which I like, but my bag has been great winter camping and summer. I unzip it for summer and use it as a cover. In winter it performs excellent.
If my current bag wasn't so reliable, I would buy the new Cloud just for the foot space.
