sleeping bag "topper" revelation

Around 7 years ago I attended a Sierra Club leaders' meeting at the Clair Tappan Lodge in California, near Donner Pass.

The last night they held a raffle and I won a Thermarest Trail Pro mattress and a synthetic top blanket that snapped to a top sheet cover for the mattress.

Finally, after all these years, I realized I could use the topper on my overstuffed 20 F. Western Mountaineering Megalite down bag for 1. more warmth and 2. to collect my condensed body vapor instead of it collecting in the sleeping bag.

So now I'll use it if the forecast is for colder than usual hunting weather and not worry about losing insulate value in my down bag over several days. That synthetic topper will dry fast when removed and aired out.

*I'm not seeing a unit like this available.
If I understand it, the quilt attaches / snaps to mattress perimeter, use a cover to your regular sleeping bag. (avoid putting sleeping mat in your bag to stay on it)
Light enough to pack without hinder.

The quilt snaps to a light cloth mattress cover that comes with it.

But I don't want to carry the mattress cover so I'm sewing mating snaps on lengths or 1" wide elastic bands that will go under my mattress and snap on the synthetic quilt. This will hold everything in place.

I'll be trying it out in a few weeks and post here how it works - or doesn't.
