The Enlightened Equipment Enigma 50 850 is a minimalist summer top quilt built around 850-fill-power duck down at an 85/15 down-to-feather ratio. In the short length it weighs just 303 g, with 163 g of down keeping the manufacturer-rated comfort temperature around 10°C — a warm-weather number that reflects the quilt's stripped-down build: no zipper, no hood, and a trapezoidal footbox that's permanently sewn shut.
Horizontal continuous baffles run through a 10D nylon ripstop shell, and the down itself is RDS-certified with the quilt made in the USA. Pad loops attach it to a sleeping pad rather than insulating underneath, and it ships with both a stuff sack and a larger storage sack for long-term loft retention.
This is a quilt for hikers chasing the lowest possible sleep-system weight on warm three-season or summer trips — the kind of gram-counting that matters on a long thru-hike. It's not built for cold margin: with no way to close off drafts around the shoulders, it rewards a warm sleeper over someone who runs cold at night.
