Hi TCP,
I haven't used the golite quilts specifically but my other half and I use quilts from
Jacks'r'Better and love them. There are also synthetic filled quilts from
MLD if you prefer that over down. In general, I think the single person quilts are better if you are a back sleeper - they can be a bit small for side sleepers. I measured up how wide a quilt would need to be to cover me lying on my side and the single person quilt from JRB didn't quite cut it. So I got one of the large size quilts from JRB (the large size from MLD would work too) and that works wonderfully.
I prefer being able to thrash around under a quilt in a way I can't in a bag, but of course that can let cold air in, so it's a trade-off. I do find in more flexible though. In warm weather my partner and I can just drape one quilt lightly over us and be plenty warm. In winter we have two quilts over us and tucked in on the sides. Together the quilts weigh less than 2kg.
Hope that helps.
