Enlightened Equipment Convert 0 950

The Convert 0 950 pairs the same -18°C winter rating and convertible, full-length-zip design as the 850-fill Convert 0 with 950-fill-power goose down instead, bringing total weight down to 894g from 973g for a comparable temperature range — a useful comparison if you're deciding how much a fill-power upgrade is worth to you in grams saved. Fill weight is 637g of 95/5 goose down, distributed roughly 60/40 toward the top of the quilt via horizontal baffles, on the logic that insulation compressed under your body does less work than insulation facing the cold air above you. The open-ended footbox can be left flat for warmer nights or zipped closed for a fully enclosed bag. Sized Regular, for users up to roughly 183cm, with RDS-certified down and PFC-free treatment. This is a genuine winter-capable quilt rather than a 3-season model pushed into cold-weather use, so it makes most sense for hikers who actually camp in sub-zero conditions and want the flexibility of an open quilt on the milder nights of a winter trip.
