I want to make a custom sized ClimaShield pillow. I'm not sure what loft to get. Is there an advantage to multiple layers of (for example 2.5) vs single/fewer layers of a higher loft.
In other words, if I determined I wanted a loft of 1.8", would there be any advantages to 3 layers of Apex 2.5 (loft of .6") vs 2 layers of Apex 3.5 (loft of .9").
I am specifically thinking of ability to fold the pillow to fit in my pack, but there might be other considerations I'm missing.
