Revelation Apex works when a down quilt fails
I have the Revelation Apex 20F in 6' length, 54" width (about 2.2 lbs). I'm 5'10", 175 lbs and can wear belay parka/pants and down mukluks inside. With less clothing, the slim width would have been sufficient. This is a bulky quilt by UL standards, at least 800 cu in without over-compressing, so be prepared for that. Early and late winter in my region, temperatures can climb just above freezing, with hosing rain and fog, then drop to single digits with heavy ice and snow, repeatedly over a single trip. With a downmat, enclosed shelter and the above clothing I've been consistently comfortable below 10F. My down quilt (lighter, less bulky, but over twice the cost -- from another maker) has been soaked flat by the dampness in the air, which is enough to form fog inside my tent. I've shortened or bailed out of a few Nov-Dec and March-April trips because of it. Climashield Apex has been the ticket to keep me hiking in that transitional weather. Damp clothing tends to dry a bit overnight; the moisture condenses in the quilt and can be air dried during the day when necessary. Less attention is required overall for the whole system to work, and unexpected conditions are more easily managed. The moderate weight/bulk penalty should be a worthwhile trade for most of my cold weather trips. Great value for the money. I've already ordered a 40F model.
