Can a 0 degree be to much quilt?

[eightweight]

I have been looking at underquilts and will be ordering an underground zepplin full length UQ with Down filling
they offer a 40 , 20 and 0 degree quilts
they also offer additional down fill for 2 oz @14.00

would I just be better off to order a 0 degree quilt ( 16 oz of fill ) instead of a 20 degree (12 oz of fill) and extra 2 oz of fill ? price differance is $15.00 and I would be getting 2 oz more fill than the 20 degree with the 2 additiona l ounces.
I will be using it in fall october and the weather can get to 30 degrees ?

so the question is if wanting just one underquilt should I get the 20 or just order the 0 degree?

Thanks Bill

For me a 20 gets me to about 25 before I start feelin like I need more insulation. A 0 would be overkill in 30 degree weather for me. You can always vent though.

The other thing to remember that the 0F and 20F will have different baffle heights. With the 0F have the thicker baffles. Adding overfill to a 20F quilt will have diminishing returns as the baffle height will be shorter and at some point the down won't achieve full loft.

It is easier to vent an underquilt that is too warm than it is to get more heat out of a quilt that is not warm enough for you at the given temperatures. I always like to have a 10 degree comfort margin for the temperatures that I expect to encounter.

If you plan to do most of your camping in the fall through winter and spring months, then I say get the 0F and vent if too warm. If you are doing most of your camping in the Spring-summer-fall months, then I would get the 20F with a bit of over fill and supplement your quilt with a torso length CCF pad, clothing, space blanket etc. In other words, get the quilt that is going to work for 90% of your needs and supplement for the other 10%.

Of course, if money is no object, get both.

Various people have nibbled around the edges of this, with pretty good results. Some day, a quilt builder will offer a system wherein 2 or more quilts can be used singly, or doubled up.

I have an incubator rated for 0* with 2 ounces over stuff and i used it into spring this year with temps in the 30s and was perfectly fine.

I've seen that done with Warbonnet Mamba TQ's. The 3 season regular will slide right into a Winter wide/long. Someone that had one of each could choose between 2, 3, or 5 inches of loft.

The JRB Standard family of quilts has always been stackable .... IE , use a Shenandoah TQ with a Hudson River UQ late spring, summer and early fall...to double up on season... Use them both stacked as a UQ and us an Old Rag Mtn quilt as a TQ for winter... Max flexability in just three multifunction quilts.

To answer the OP's question directly, "if wanting just one underquilt...", I'd have a 20* first. Reasoning is that it can take me to the greatest range of temps comfortably. I wouldn't hesitate to use it throughout the summer and I've been under 15* with proper dress.

I found out a long time ago, venting a zero degree sleeping bag or top quilt doesn't always work. The problem is if your too warm at 30 degrees and you vent, the body part near the vent freezes and everything else is still too warm. Bottom quilts are a different story, they can be vented and it seems to work for the full length of the quilt.

I would recommend the 20 degree with draft collars and 1oz overfill
