Effective Temperature Rating
There
is a Rating formula from "Beyond Backpacking" by Ray Jardine that is
helpful in determining how many layers of insulation you need. ETR=100-(40xT)
ETR = Effective Temperature rating
T = the quilt or bag's thickness, in inches, covering the person.
When we multiply the thickness wanted by 40, then subtract the result from 100, we arrive at the ETR, the quilt or bag's Effective Temperature rating, in degrees Fahrenheit." Ray Jardine
Also helpful are a couple of the manufacturer links:
Here is the link for Primaloft: http://www.albint.com/primaloft/
