I bought 3 yards of Insultex, and 3 yards of 1.1 ripstop nylon. I kept the Insultex as a continuous roll, and just layered the roll three layers deep. Ended up with 3 layers about 40" x 60". I sandwiched the insultex between the ripstop, folded over and sewed it.
I then sewed the ripstop and insultex together to keep the insultex from shifting, added shock cord, cord locks, and adjusted fit to loosley hang under my hammock. The Insultex was not compressed when I laid in the hammock.
This past weekend I went to a national forest to test it out. Temperatures dropped to about 55°F, with a bit of wind, and a slight drizzle.
I was cold.
I had a 50°F fleece sleeping bag as a topquilt doubled over myself, was wearing synthetic DWR pants, long sleeve underarmour shirt, wool socks, and used my fleece jacket under my legs.
About 2AM I had to take out my 35°F Wilderness Logics underquilt and used that as a top quilt to stay warm.
So, how can I modify the 3 layers to adapt to cooler temperatures? I have ripped the threads out and am now looking at starting over. Would like some advice from anyone that has worked with it and had better success.
I have followed the sticky, however I did not cut pleats in the Insultex layers (i wanted to preserve the insulation in case I had to start over). I still have 3 yards of insultex, and the original ripstop nylon to work with.
I see some are adding several folded over sections lengthwise to separate the layers, how is that working out?
Or, has anyone added channels between the insultex layers so that it will loft itself?
