Overall I like the EE quilt and it’s a go-to now but for very specific temps/ weather forecasts/ elevations. For a broad conclusion I would agree with many reviewers that this is NOT a 20F quilt. For more read on.
For context in my review I’m age 62 and an experienced thru - hiker ( PCT’17) and backpacker. I travel fairly light but not hardcore UL. My baseweight would be around 12 pounds +/- depending on the trip. I have a number of bags and another quilt: Marmot Phase 20, EB Kara Koram 20, Mountain Hardware Speed 32, and a Feathered Friends quilt which I had overstuffed to bring it to 15 F.
I used the EE Revelation quilt on a 205 mile section hike on the PCT in NorCal( Sierra City to Burney) in June of 2018 and most recently ( Sept 9-13, ‘19) on the Wonderland Trail around Mt. Rainier. I typically wear clean dry base layers and sleeping socks with any sleeping set up and add additional clothing layers as required.
Pros: very lightweight and good weight to warmth ratio
Versatile and easy to use. I really like how the Revelation works with a sleeping pad and how it can be configured for temperature variation.
Roomy. I’m an active sleeper and the way the Revelation fits to a pad allows the sleeper to move around inside the system without the quilt twisting. This inherently can let drafts in if the bag isn’t secured snugly around the pad.
For my NorCal section hike last year the Revelation was perfect. Nights, even at elevation, didn’t get below 40. I was never uncomfortable wearing a merino bottom, a Patagonia thermal weight hoody and sleeping socks.
Cons: The biggest one is not as advertised in terms of temp rating. On the recent trip around the Wonderland Trail the quilt was a bit of a fail at elevation. Temps dropped to freezing or very close. I was using a full size Exped mat. I was wearing base layers and a Ghost Whisperer down jacket with hood. I took a pair of Ghost Whisperer down pants to use as a pillow ( and “ just in case” ) and ended up wearing them most nights.
Even with those layers I was uncomfortably cool. For this trip, expecting rain and damp conditions, I left my single wall Six Moons at home and used a Copper Spur 1.
Also agree with other reviewers about large gaps of no fill in some of the baffles. I’m sure a spin in the dryer will remedy that but it’s typically not how you want the product to be out of the box.
So, for me this is basically an excellent summer quilt and would only use it on the shoulders at the right elevations and weather forecast. I will also bring my silk liner next time it comes off the shelf to add a few degrees of overall rating
Would recommend to a friend.
