I am trying to figure out when used with a 20 degree underquilt... I suppose 10 degrees ?

I know everyone is different. Some people sleep warmer than others. But for some sense of numbers I was trying to figure out what the rating could be.

Think of it this way. If a WM pad is good for Mountain Gout to better than 35F, then that is at least 35* worth of protection for him. 70 minus 35 = 35* of protection. Whether or not he adds an UQ to that pad, it should give him that much protection all the time.

Now, what if he is good to 20 in that 20F rated UQ, giving him 70 minus 20 = 50F worth of protection? and what if he now adds another 35F worth of protection to the total, won't that be about ( ball park for real life ) 85F total of protection? I know most folks don't want to count adding a pad as good for that much ( one reason to be discussed next paragraph). But, if a 3" thick quilt is good for you to say 20F, or 70 minus 20 = 50F worth of insulation, divided by 3 = more or less about 16.6*F protection for each inch ( single layer ) of down insulation. Now will any one deny that adding about 1 more inch of insulation will by you roughly another 16.6* of warmth? Of course it will, approximately. Hence, a 3" thick JRB MW3 is rated for ~20, while a 4" thick MW4 is rated for ~ zero, as expected.

So, if instead of adding another 20F worth of protection by adding another inch of down, you added 20F or more of protection by adding some thickness of pad, why wouldn't we expect it to work the same way. Just another form of layering.

But one caveat: there are things to go wrong with the pad effecting the quilts fit. Even more so, I suspect, with wider and maybe longer pads. So Mountain Gout should still get his warmth to the 30s laying on top of his pad. But it is not as certain that he will get another 50F of warmth ( to minus 20F ) by adding the +20F UQ. Because perfection of fit is everything with an UQ, and if that pad causes a poor fit somewhere along the quilts edges, that 20f quilt will suddenly become a 40F quilt or even a 50F. But even at 50F, you are still adding another 20* of warmth to whatever the pad gives you. Theoretically, anyway. YMMV! :D

So I am considering options to expand the temperature range of my gear... does anyone have experience adding a pad between the layers of a DL hammock with an UQ?

I used to but used an SPE since my hammocks are single layer. It works and will get you to much lower temps.
A UQ Protector also helps....scroll down a bit. http://www.2qzqhammockhanger.com/ham...cessories.html
