Came up with an idea for a SUL Quilt that I guess I will have to make now.
It will be similar to my sub 10 ounce quilt in the way it is made.
It will have a single layer of fabric on the bottom where your body would compress the down anyway.
The shape and width will be the same.
Looking at a 13 ounce quilt with 1.25" baffles and at least 6.5 ounces of 900 fill down.
Actually I'll probably use 850 fill as it's much cheaper and I cannot tell the difference, (probably the only difference is a few feathers in the 850).
Will use Nobul1 for the inside and M50 outside.
I will use a velcro for the neck area instead of sewing the neck down.
This will give me the ability to open the quilt up if needed. I like having the neck closed down like you see in the pictures. It traps the heat in and gives you something similar to a draft tube around your neck.
The biggest change in the make of the quilt is that it will have vertical baffles and one side will have the baffles end about 3-4" from one side of the quilt.
This will give you a single length chamber that you will be able to shift the fill from one chamber to another.
The idea behind this is to go from a 2 season quilt to a 3 season quilt when you shift the down tho the bottom 2/3rds and use it with a down jacket.
I figure the 2 season would get you down to 45 and probably 35 with the jacket, (I sleep cold).
This style quilt actually works better with a hammock or even a full length pad.
Of course the full length pad kind of contradicts the SUL weight.
My sub 10 is much warmer than you would think it would be for 9.8 ounces as it encompasses your entire body and traps the heat in much better than a standard top quilt.
I actually got this idea while emailing some info back and forth with John from Hikelighter.com.

You constantly make me think and rethink things.Jul 2, 2013 at 8:39 am #2001656

How is the baffle design different than the Karo Step baffles from Enlightened Equipment quilts? I like the idea though, would keep the most down over your torso instead of slowly falling to your sides over the course of a night.Jul 2, 2013 at 10:12 am #2001693
It would be the same concept as a karo with baffles.
I thing if you tried to move all the down out of the upper 1/3 about half the original down would shift back in over the night just do to the difference of pressure.
Having a 3" chamber on the side would make it harder to initially shift the fill down but would stay put once you do.Jul 2, 2013 at 10:10 pm #2001923

Not sure I am understanding the whole concept. I get the vertical baffles, and also the layer of fabric underneath, but how is it different than a Big Agnes bag (pad sleeve underneath), or an old WM Pod bag? I think i'm missing something here….

Difference between the WM Pod?
It's a quilt version with the same loft and will handle drafts better and has much better venting options in warmer weather.
It is also 5 ounces lighter and would double as an elephants foot for even lower temps.
Same concept as the WM Pod really but a lot more versatile.
It's not like all of my concepts work anyway.
Of the 12 or so quilts and bags I have made, 10 of them have all been completely different. They just seem to find a niche that can fit into any trip I take.
I kind of like to push the boundaries yet I am a cold sleeper so pushing the sleep system is the best option.Jul 3, 2013 at 1:50 pm #2002173

My experience with karo baffles, on my EE quilt, wasn't great. The trade off between being able to move down around and effective down control needs to be very carefully managed.
Many moons ago I think Gossamer Gear had a quilt available with fabric on the bottom.
Will be interesting to see how this works out for you. I am always amazed by what people managed to produce by their own hand.Jul 3, 2013 at 3:39 pm #2002219

My EE quilt weight 19.1 ounces and it has 12.9 ounces of down.Jul 3, 2013 at 4:06 pm #2002234

Thanks for answering my question, Aaron. Now we need pics from the field.

I am working on a polycyro tarp with a single pole set up first.
I'll still need to get this done while the weather is still good.
