I was thinking, why is it rare to see insulation products use 900 fill down instead of the standard 800 fill down that most companies seem to use?
The only product I own that uses 900 fill down is my Montbell Ex Light Down Jacket, and it has a very aggressive warmth to weight ratio.
I am planning on purchasing a quilt from Nunatak next year and I'm wondering if I could request 900 fill down (I don't even want to imagine what the price increase will be though).
