I’m shopping for a 20 degree quilt. Goal is to control weight and packing bulk without making the quilt “stupid” light or so fragile that it falls apart under regular use. 950 fp down is my insulation of choice. I take good care of my gear and don’t abuse it. I’m in the northeast and, honestly, I’m mostly a fair weather hiker-camper. For use in a hammock but I think the discussion would be just as relevant in a tent.
10d and 7D are the two fabric offerings on my radar. The weight difference is maybe two ounces depending on which maker’s site I’m shopping. Pros, as I understand them, of 7D is that it’s lighter and packs smaller but a bit more delicate. Pros of the 10d is that it’s a bit more wind resistant and durable but a tad bulkier to pack.
Does anyone have experience with both fabrics? Please share your thoughts.
Is there any reason to mix and match; for example, 7D inner fabric and 10 D outer? I see EE offers this option.
Thank you.
