im making a quilt ... im wondering if a single layer of 3.0/oz primaloft one, which is maybe 5/8 of an inch thick, would be warm enough to stay warm to about 30 degrees
I tend to sleep warm and that wouldn't work for me.
I have two quilts, both using M90 fabric, one with 3oz Climashield Apex that is good to about 40F and another using "6oz" Primaloft One (but actually weighed out at about 5oz) that is good to about 25F. The two of them together is OK to about 0F. Apex and One offer about the same warmth per ounce.
But I'm curious, what is your source of 3oz Primaloft One?
