Warmth on cold nights
I'm a cold sleeper, and even a 20F degree Revelation has been chilly for me, now that I'm backpacking in the late shoulder season and through winters. I am also backpacking at elevation these days, so a comfortable sleep is critical during the long winter nights. I bought a 950 fill, 0 degree Enigma specifically for cold weather camping, and have had a few trips now with this new quilt in my backpack. Truly wonderful, warm sleep as the weather went well below freezing. For the first time in years, my feet stayed warm thanks to the enclosed footbox of the Enigma, and the high fill 0 degree rating ensured enough loft to keep me comfy and warm throughout many nights when frost covered my ground and tent, or it outright snowed. My custom Enigma is now my go-to bag for cold weather camping and backpacking. Sure, the temperature rating and fill for my bag were costly, but given my years now with my 20 degree Revelation, I'm confident my Enigma will be with me for many years to come. I certainly wouldn't take a 0 degree bag on a summer trip, due to volume and warmth (no need for lots of down when the night time temps are 50F, for example), I can see where this would be a good companion in higher elevations regardless of season, as well as the true shoulder season, when night time temps can be unpredictable. I highly recommend the Enigma for folks whose feet are cold at night, and those looking for colder weather sleeping systems. I love the combination of quilt and enclosed footbox!
