The Revelation 40 950 sits toward the warmer end of the Enlightened Equipment range — a limit rating around 4 °C puts it closer to a summer or shoulder-season piece than a true all-around three-season quilt. It hits a low 420 g by pairing a modest 246 g fill with 950-fill-power goose down, the highest fill power in the line.
A draft collar limits warm-air loss around the neck despite this being the lightweight summer build, and an open footbox plus pad attachment loops round out the typical top-quilt construction. The 192 cm internal length fits users up to 183 cm. The 10D nylon ripstop shell and RDS-certified, PFC-free down match the rest of the lineup's standard, and it's made in the USA.
For ultralight hikers planning warm summer nights who want the lowest possible sleep-system weight, this version is one of the lightest choices in the range — at the cost of having little thermal margin if conditions turn colder than expected.
