That sounds like the type of equation an engineer or physist would use.

65 (a bit of a cold sleeper) - 10 (It is Winter) = 55/10 = 5.5 - 1 = 4.5" of loft?

Wow.

Or just for one quilt? I'm a cold sleeper, but that doesn't make me a cold person, does it? Last edited by NCPatrick; 02-22-2007 at 14:19..

That's for all-around insulation, so that would be 4.5" top AND bottom...if I'm reading right. And yes, cold sleepers are cold people - they're ornery because they have to carry all that insulation (not because of their medulla oblongata)!

Me personally 2.5" will get me to about 20 deg F. Throw in the rest of my hammock gear with that same bag and I am good well below 0 deg F. __________________ Is that too much to ask?
