Hi,
My two cents worth:
I have had a MontBell Downhugger #3 for about 5 years, it is rated to 30F(-1) and it has been a great bag, I sleep comfortably down to 0 deg. as I am a warm sleeper, my wife is not and she gets cold when it creeps below 8 - 10( but she is a bit extreme) don't tell her I said so though.
We once had them when it was -10(In QLD!), we were very friendly that night! I can't answer for if the stretch bit is a gimmick or not, but even if it is, MontBell makes very good bags. The new 900 fill Downhugger #2 would get my vote, only 680g. If you worry about really low temperatures, get a MontBell down inner vest to use as a booster when the weather forecast looks iffy, leave it at home in summer, we have them and they are fantastic.
Cheers.
