Enlightened Equipment Revelation 850 DT 20°F

The Revelation 850 DT 20°F shares its core spec sheet with the base Revelation 20 — 0 °C comfort, -7 °C limit, 320 g of fill, 570 g total weight — with one key difference: DownTek hydrophobic-treated down. That treatment slows moisture absorption in individual down clusters, helping loft hold up longer in damp conditions than untreated down manages. Shell and liner both use 10D nylon ripstop, and the differential cut and trapezoidal footbox keep the build in line with the rest of the range; pad attachment loops are standard top-quilt fare. The down is RDS certified, PFC-free, and made in the USA with the usual one-year warranty. For hikers expecting damper conditions — morning condensation in a single-wall tent, a wetter stretch of trail — the hydrophobic treatment is a reasonable hedge against the main weakness of untreated down, without stepping up to heavier synthetic insulation.
