Hi Perry
Was it the EE Prodigy with 2.5oz Climashield Apex you ordered?
As I understand it, you want to be able to insert an extra filament layer inside the quilt, against the existing filament. I think this would be doable as a once off, but I suspect that repeatadly inserting and removing it would lead to a breakdown in the filament before long.
An alternative would be to buy or make a down quilt. You could then combine the quilts for a great winter sleeping system - down quilt inner, synthetic quilt outer - and use them separately as appropriate for other conditions eg. synthetic quilt for summer, down quilt for autumn & spring. Would be a great project to do.
On the other hand, if you just permanently add another 2.5oz layer, you will find you can use down to some pretty cool temps, if you're dressed for it. It got down to -4C on Mt Arthur a few weeks back, but I was quite comfy (wearing socks, thermals top & bottom, gloves, fleece cap, fleece top, down vest)
I don't know of any Oz suppliers for this stuff. I went to Thru-hiker in the US.
