Enlightened Equipment Convert 0 850

The Convert 0 850 is Enlightened Equipment's cold-weather take on their convertible quilt design: a two-way, full-length zipper and an adjustable, open-ended footbox let it run as a flat open quilt on milder nights or zip into a fully enclosed sleeping bag when the temperature drops. Rated to a -18°C limit, it sits in EE's winter-season tier — a genuine step up from the 3-season Convert models rather than just a colder-sounding number. That warmth comes from 663g of 850-fill-power duck down, which explains the 907g total weight — noticeably heavier than the 3-season quilts in the same lineup, but reasonable given the temperature range it's built for. Vertical box baffles help keep that much down evenly distributed rather than shifting toward one end of the quilt. Available in Short sizing, made in the USA, with RDS-certified down and PFC-free DWR treatment, it suits winter backpacking or shoulder-season trips where genuine sub-zero performance matters more than shaving grams. The convertible design adds versatility that a pure open quilt or a dedicated winter bag can't offer on its own.
