Bear,
The Helium is the 15 degree model (the Hydrogen is the 30-40 degree bag). I'll undoubtedly be draping it over me instead of getting inside on a warm summer evening but I don't have anything lighter.
I've used the Helium down to around 20 degrees under the Tarptent and it was comfortable. The most amazing thing is that it weighs 1 lb 13 oz. and is plenty roomy for a guy who is 6 ft. and about 225 lbs (on a skinny day).
Sasha: I believe they have changed Tarptent models quite a bit since I got mine from the original designer about 5-6 years ago. I've used it in some high winds and rain successfully. It once took approx. a 4 inch snow load---which is about its limit.
