I saw an ad for "poly-fil" polyester fiberfill at Walmart that reminded of something I read on wiggy's website about random fiber arrangement versus fibers running in the same direction. The "poly-fill" can be seen online at http://www.poly-fil.com/fiberfill.asp
So I'm thinking, what if I buy a bag of this stuff for $3.00 and fill 12 zip lock bags (cost for box of zip locks was $2)with it and stuff two each into each of the 6 pockets on the Clark Jungle hammock? Will this stuff provide any insulation? Well, I'm going to find out tonight if the temperature drops, but right now is warmer than it was last night. We had a good breeze blowing this afternoon but it has died out so I might not get a good test tonight.
But if it does offer insulation, then the next question will be whether it will bounce back after a day of being compressed. I can almost flatten the bags by opening just a half inch of the top and squeezing the air out. And if I then reopen the bag, the material fluffs right back up. I'll test it tomorrow to see if it will do so after a day of being compressed.
