I'd like to simulate the pillows for insulation that constitutes most of the Clark Z-liner system. Call it proof in concept.
So you needn't bother to look at www.junglehammocks.com, Clark hangs a second bottom divided into from 2-6 pockets underneath their hammocks. It climbs the sides, and is sewn with a 2" baffle at the bottom and gathered elastic at the top. 6 pockets covers most of the bottom that would be covered by an 3/4 length underquilt.
Just now, Wal-Mart is selling US-made standard size all-polyester bedding pillows @ $2.50. Dunno that batting can be had cheaper, not even from the same WallyWorld. The pillows are sized well for the Clark pockets, but with way too much loft, about 7". And yes, I know, way too much weight, too, at 15oz each. But, I'll open them and distribute the stuff to one or two other pillow casings. And the weight of the Clark "system" is $179 + shipping. vs $10 for these materials.
This all for trial -- I could use plastic bags or recycle pillow-casings from old ones. If it works, I can make 6-7 lightweight tafetta sacks.
Now a general question on polyester batting sourcing from cheap polyester pillows: Given a choice, do I want for underquilt use, to look for pillows which are firm or soft?
I'd appreciate key-words or URLS or suggested threads on this.
