Climashield ratings again on 10/06/2010 19:23:51 MDT Print View

Sorry about asking this again, but want to make sure I get this right.

I read through some info here and online
and looked through the CLO numbers and am a warm sleeper.

Want to build a 20dF inner quilt with a closed footbox and a 40dF topper/summer bag.

From what I have found 5 oz climashield should take me down to 20-25dF and 2.5 oz climashield should be good for 45dF.

Any guesses on the combo ?? I figure maybe 10-15.

For a Hammock UQ down to 20 what would I need for the bottom. I am thinking probably 2 layers of 3.7oz combat.

I guess it's always all personal. I made a hammock underquilt with a layer of 5 oz. climashield, and I personally would trust it down to no lower than 30. I have a top quilt from the 2.5 oz. weight and I would use it no lower than 50.

So that's my two cents!

50dF for 2.5 is good. I want it mostly for a summer bag anyway.

If 5oz works at 30Df for a bottom quilt I would think 7.5 oz or a layer of 5+2.5 should be good to 20dF.

Thanks

I wouldn't take my CS 5oz quilt out below 30 without additional clothing or other layers.

Troy,

That's a lot of bulk you're looking at. I too made a climashield top quilt for summer out of 2.5 oz stuff. I think that's a perfect use for it, because a down quilt is hard to make that thin. However, I wouldn't want to pack any more climashield than that.

Troy, I think a couple people might be suggesting the same thing you wrote in your OP, though differed with your self:

You said you thought a double layer of 3.7oz might take your UQ to 20F, but that you thought a single layer of 5oz would be good for a 20F quilt. Doesn't jive.

Personal experience, 5oz isn't gonna hit 20F at all. Maybe 7.2oz, I dunno. Also note other Climashield options under "insulation" at OWF.

I don't know the ins and outs of insulating hammocks but on the ground with pads providing > R5 beneath me a quilt that keeps me warm at 40F over another that's kept me warm at 30F is OK to 0-5F.

The 40F quilt uses 2.5oz XP that has been augmented with a partial additional layer in areas where it is thinner than the other areas ... averages 3oz.

The 30F quilt uses 6oz Primaloft One, which should be warmer than 5oz XP. It might be good below 30F but I haven't found the right night to confirm that.

The two together leaves me cool enough to wake up and not get back to sleep at slightly below 0F.


I would expect that you'll want the hammock under-quilt to be as warm as what's needed on top
