Ultra Cold Top Quilt

[BillyBob58]

I've never seen quite a match for that! So is that 7" loft in the single/top layer? 7" on top of you? If so, what is that, like minus 60F if drafts can be sealed out?

Theoretically is should be good in the -70 to -80 range depending on the scale... I doubt that I will ever manage to see those temps, but it should be quite cozy in the -20 to -45 range. I suspect it will make getting up in the morning just that much harder.

WOW,,, some major loft happening there.

Fabric + 78 ounces of fill....what does it weigh.... 5 1/2 pounds?

I don't think I would ever get out of hammock.

"After going missing for two weeks, corrupt_reverend's body was found in his hammock. He had a smile on his face when search and rescue found him. Cause of death is suspected to be an overdose of cozy."

I'd like to, it will just depend on scheduling. The boss might not approve of back to back trips. It will at least be getting several nights worth of testing in the backyard if I can't make it. I did test it out sleeping in the recliner last night -- very comfy.

I've never been down below about 0°F but am wondering if you now need to use a vapor barrier with such a lofty TQ? At extreme temps will not the moisture generated by your body now be trapped and condense inside the bag?

Yes, I always use vapor barrier clothing for sleeping in extreme cold. I have a couple of these, that I like for sleeping: www.realsaunasweatsuit.com. If I'm not taking a pulk, I'll use a set of light weight silnylon rain gear. The one issue I'll need to test to see it how much condensation I get from my breath overnight on the giant wall of down just below my chin. I have a balaclava with a heat exchange that I plan on testing to see if that reduces the moisture output.

If that doesn't work I may have to add a Shug style frost bib, or fleece protector at the top to collect the condensation.

That's one behemoth bad boy top quilt!

Love it

The heat exchanger mask will help BTW, I reckon it reduces my breath condensation by about a half.

Fantastic job on your quilt.
