So im going to order some primaloft.
Im a bit confused about the weights. This one is 6oz per sq meter. http://www.extremtextil.de/catalog/P...200g::715.html
Would i need to have two layers to get down to 20F.
Need your opinion on this as im ordering soon and dont want to order too much.,
Also is it neccessary to quilt primaloft?
If so what is quilting and how is it done as i just dont get it?
