The Convert 20 950 pairs the -7°C limit rating of the Convert 20 line with 950-fill-power goose down, bringing total weight to 699g against the 750g of the 850-fill sibling for the same warmth class. That 51g gap is the practical premium of a higher fill grade — noticeable but not dramatic at this temperature range.
Fill weight is 455g, held in place by continuous vertical baffles, and the full-length zipper is what lets the quilt switch between a fully open blanket and a zipped, enclosed sleeping bag as conditions change through the night. This flexibility is the main selling point of the Convert series over EE's simpler open-quilt models.
Sized Regular for users up to roughly 183cm, with RDS-certified goose down and PFC-free DWR finish. It's a solid pick for 3-season backpackers and thru-hikers who want one quilt that handles both mild evenings and colder nights without carrying a second, warmer piece of gear, at the cost of paying more for the fill-power upgrade.
