I'm importing what you posted on the SLEEPING BAG BONDAGE SURVEY 'cause this is something you'd previously mentioned in one of your reviews here, which I forget to comment on.
Being the guy who owns the -60c-rated bag that you've seen in this story and also being someone who produces a lot of body heat, I think I'm well placed to address some of your insecurities when it comes to sleeping bags and overheating.
Guys who are new/unfamiliar with expedition-grade survival gear are often genuinely surprised at how crazy thick yet comfortable these bags are.
Unlike a lot of synthetic insulation materials, down actually breathes quite well.
Depending on the liner material, that's also why down puffers and vests are generally a lot more comfy to wear than their synthetic-insulated counterparts.
Heavy-duty down bags (even the extremely overstuffed one's like Nick's) are generally a LOT more comfortable than most people realise.
I won't lie though, the smothering can be intense if your face isn't perfectly aligned with the hood opening.
The more heavy-duty the bag is, the smaller the hood opening tends to be. Ex: Nick's bag only has a hood opening that stretches out to 6-7 cm max.

As far as overheating goes, the bags are designed to keep you really warm but dry.
So unless you're using them in completely inappropriate settings (ex: in warm weather) the breathability makes all the difference.
And yeah, it's been confirmed to me that bags like mine (which has been used extensively for long camping trips) do carry the natural scent of their owner quite strongly. That fact was never voiced to me in complaint though. Just sayin'

Steven's been picking up on that a lot, not only with Nick's crazy fat bag, but with Nathan's as well.
