Prequilting SynthIsolation for removable layers TO WHAT

I'm thinkering around with the idea of an adjustable synthetic quilt(layers exchangeable OTG).
To avoid cold spots i'm planing to overlay at least two layers with the staystitch(right word?)shifted
and the layers only attached to eachother on the boarder.

Well it just occured to me that it is not as simple as i imagined as i need something else to quilt the Primaloft to.

I imagine someone here must already have done something similar ?

I know of Vlieseline and such but i dont know what weight is available i think someting around 0.5oz would be ideal?
What should i be looking at?
What material is there and would you use a continuous layer or cut out alot of windows so the additional material is only running along the stay stitch?

And if someone here knows the Primaloft, would the scrim that it comes attached to be sufficient on one side?

i've done a removeable layer uq. i attached one permanent layer by stitching it in only along the peremiter, and then quilt loop the additional layers to the perimeter of the permanent one.

i was using continuous filament though (cl xp), primaloft sport needs more stitching and stabilization, and primaloft one needs ALOT more

never worked with either primaloft though, that's just what i hear

i'd probably go with continuous filament since it doesn't need as much stabilization

Unfortunately Continous Filament Insulation is not readily available over here i'm stuck to PL!.

Although the figures look quite different once you add the scrim layers to the weight
(0,02-0,025clo/g asuming 16g/m² and rectangular cutouts for the scrim) i still think it's worth it due to the availability and the otherwise favorable properties.
Climashield looks alot easier to handle though :mellow:


I hope i can find a non-woven/scrim around 20g ,no idea were to start looking though


Do you think attaching the additional layers with a small loop and button or similar through sewn button holes on the perimeter could hold instead of the quilting loops? Assuming the hole itself is not torn open

Yes, and that synthetic UQ you make is an excellent piece of gear.

As Primaloft is more common over here i got an answer on a german forum,
for the case anyone comes across some primaloft and wants to try it, i'll summ it up here including the answers i got on the german forum ODS

Primaloft is a loose filament insulation material, it needs to be quilted to a supporting layer.
In order to avoid cold spots due to the quilting, using 2 or more layers of primaloft with offset stitching is a common implementation.

If for some reason the insulation cannot be quilted to the shell layers the scrim layer it comes on can be used for support.
Other materials notably Vlieseline H250,G700,G785 and substitutes can be used aswell.
When working with the Primaloft one needs to prevent the needle catching on the filaments
as it would draw them into the machine and thus might tear it. To do so a thin paper (newspaper etc.)
or stripes of one of the aforementioned scrim layers can be placed along the stitching lines.
It can be removed after the sewing as the thread will not cut trough the Primaloft or left there to further prevent tear off under harsh handling

It is, isn't it? ;) ( I say that as one of only a few who own one).

Ha i wish i could be in that luxe aswell, it certainly sounds like a very nice thing:laugh:
Hope i will end up with someting usable aswell,after the certain discovery that i could have been happy way easier with something aftermarket ...

I like the idea of buttons holding the two layers together. Or combination velcro and buttons. Have to think of field repair, should you lose a button or two on the trail, what would you use to hold the two layers together? Strategically placed strips Velcro would give you a good backup connection, as well as a little more staying power to keep pressure off the buttons. Probably better ways to skin this cat, but I like the idea in general.

Right now my plan is to make button holes in my insulation layer but fix a short piece of string/ribbon/folded fabric at the corresponding place of the shell and knot it to the buttonhole.
Maybe it makes even more sense if this piece is not sewn on but there is also a button hole on the shell, so there are more options for field repair

I would not serge the shell but leave ~1/2 - 1 inch of fabric on the perimeter to place those holes /fixtures.

I think you're right though a larger surface attachment would be good, i think velcro is quite heavy though

Good plan - but velcro being heavy? You must be a UL guy.:D

The ribbon ties are a great idea - easy field repair, rather than losing a button on the trail. And you could strip a flexible piece of bark to use as a tie in a pinch, or a thin feeder root from something like an aspen. I've used that as string in the past.
