The Regular-cut Revelation 30 850 is manufactured in Minnesota and targets the standard three-season range, with a limit rating around -1 °C. Its 365 g of grey duck down at 850 fill power carries RDS certification, and the 192 cm internal length is sized for users up to roughly 183 cm.
The open-style footbox, without a fixed closure, makes venting easier on warmer nights, while pad attachment loops keep the quilt in place. The 10D nylon ripstop shell with a DWR finish brings total weight to 544 g. Both a stuff sack and a storage sack are included, the latter meant for keeping the down lofted during long-term storage.
That combination of lower weight and a reasonable temperature limit makes the Revelation 30 850 a balanced choice for hikers looking for a sleep system suited to weekend trips and longer three-season hikes without excess weight.
