PapaSmurf, that's great info. Thanks! I think your IX + Primaloft idea is a good one. My limited experience with synthetic underquilts leads me to think that the heavier the quilt, the harder it is to fit to the hammock without air gaps, but I see a real need for a cheap summer-weight UQ.
Hangnout, the scrim that comes with sheet Primaloft isn't bonded to it, and IMO its main benefit is to keep the rolled primaloft from tangling with adjacent layers as it's being unrolled and sewn to fabric. There's even a question about whether the scrim is necessary while sewing, once the insulation is unrolled. Thanks to RamblinRev I now know to put the fabric on top of the layer of insulation while sewing. It doesn't catch in the feed dogs, but I used to have problems with it catching on the presser foot doing it the old way with the insulation layer on top.
Papasmurf i thing it's a good idea for summer weight UQ i agree with WV if it starts to get too heavy it might not be worth the weight
but i would like to see what you can come up with maybe a summer UQ under $100 and under 20oz ... that would be a hot item with members that can't dish out $200+ for a down UQ
It puts the Underquilt on it's hammock ... It does this whenever it gets cold
There's nothing shabby about 550 performance.The best bags ten years ago were filled with 650-rated down. If they were used much, 550 would be less than a 15% degradation (assuming loft = performance.)
I'm currently thinking about an underquilt tutorial using this fill combined with IX for Scouts, Car campers, and folks who just can't afford the good stuff. Would there be interest in the HF community for heavier budget underquilts and top quilts?[/QUOTE]
Also us folks looking at a lot of dampness. I just picked up a pair of poncho liners to play with. I'm starting to think of a multilayer TQ with a PL, "poncho" wind block layer, and a double wt PL equivalent. Mix and match as needed.
Its not always "affording" the so called good stuff. I decided I'd use synthetics on my diy tq and uq for personal reasons. I decide on primaloft after my wife got a Patagonia jacket with it. She's cold natured, and it packs down very nicely, plus keep her chill off...
Now I see I have an other options to think about, loose fill....
"truth is uncontainable, and inexpressible. It neither is nor is not.
This unformulated principle is the foundation of the different systems of all the sages."
From PrimaLoft's website there are a bunch of different types ranging from Infinity to One, with One having the best performance by far.
For example, One has a clo/oz/yard2 value of 0.92 when dry and 0.90 when wet. Going down just one level to Sport has a clo/oz/yard2 value of 0.79 when dry and 0.72 when wet.
I sent a query in to DownLite to find out what PrimaLoft is in the loose fill.
What do you think about the differences between PrimaLoft One and Sport? One has more insulating capability but acts as a windbreaker too (I assume because the fibers are so fine). Sport doesn't have windblocking capability according to their website.
Is the windblocking capability of PrimaLoft One going to cause condensation problems?
