any other non lofting insulative ideas for blankets/quilts?

Try Insultex.

Great stuff and tons of info @ hammockforums.net. Tree to Trail Gear makes some gear from it.

Have you looked at Insultex? It needs two or more layers, each separated by an airspace. It weighs 1.35 oz/sy. Although the material isn't breathable, it is sewn to a scrim on both sides, creating hundreds of needle holds. It's easily sewn. You can leave it exposed if it won't be abraded or contact the ground. Otherwise, a nylon cover can be sewn to it. BTW, it is waterproof.

That stuff looks great but I couldn't find anything about it at the Tree to Trail. Looks promising though.

Okay, I think I get it, it is the IX stuff.

I want some to play around with the heetsheets.

I tried a partial Insultex under quilt. It was okay, but not breathable and nothing earth-shattering in the insulation world. What you are getting is a layer of polyethylene foam with a scrim quilted on each side. The foam is the thin white stuff you see products packaged in. You end up with a dash of vapor barrier and wind blocking with a pinch of insulation. It is light and folds up well for travel. The manufacturer makes a claim of a CLO of 2.0, adding an additional 13F insulation for one layer with a product that is 0.5mm thick. I think not. http://insultex.com/index2.html

This video gives a good look at an underquilt made of Insultex with a nylon outer shell.

I just ran into a Pellon product called Insul-Fleece that looks promising for light blankets and quilts for hammocks. I have no idea what the weight is. I ordered a couple yards to try in a double layer hammock. http://www.fabricdepot.com/index.php?page=ProductPage&pageid=160132

Manufacturer's description:

"Insul-Fleece Metalized mylar is layered between polyester fleece to create a high-quality barrier that reflects heat or cold(polyester fibers resist conduction while the mylar resists radiant energy). This special combination is very flexible and easy to sew through, and can be washed and tumble dried with no bunching. Ideal for making pot holders, oven mitts, etc. Can also be used in lunch sacks and grocery totes to keep ice cream and drinks cold or deli food warm!"

I have used agricultural fleece (polypropylene spun-bonded floating row cover) for a warm-weather MYOG sleeping bag. It worked really well, and the roll of material I bought was laughably cheap. I used it with a heetsheet, and I think that combination would be perfect down to about freezing for adventure racing or some other application where disposable gear is acceptable.

IMO, based of earlier threads, the 3M Thinsulate is still the best nonlofter, but it does not compare to the best lofting insulation in terms of insulative value for the weight.

Liked the idea of Montbell for the thin draft tubes, though, and plan to use it in a Thinsulate draft tube of my next MYOG bag.

Also like the idea of building a bag that does not stitch down the synthetic insulation, but allows it to fully loft as a down bag does. Am trying to figure out a better way to do it without baffles. There are some threads on T-H about doing this with Climate (or is it Climatex?), but nothing yet on doing it with insulation that needs more stabilizing.

Inadvertently gave the wrong name above…..sorry about that. Check out the Molly Mac Gear.
