I purchased a from stock Revelation 30 degree (850, Reg, Reg) which went on a three day into the Desolation Wilderness. The temps during the second night dropped to about 34 degrees with very gusty winds of which I set up a tarp that night to help stave off the winds. Underneath I used a Therm A Rest NeoAir XTherm. With this setup and properly fit to the pad it undoubtedly hits its temp rating and then some. I had to open it up as I had been a bit too warm. It packs very well, easily providing me more than enough room in my Osprey Stratos 34 for the three days this time of year. I'm so happy with it I will be ordering another for the summer season.
Revelation XL 30 deg
This is my first quilt purchase and so far I like it. I was thankful to find this style of sleeping bag as I had always had the problem of getting too hot in previous quality down bags I had and had ended up unzipping the bag and sticking my feet outside to cool off. When I found the Revelation it made me wonder why I hadn't thought of the very design myself. I hadn't actually purchased the quilt to backpack with, but for just sleeping in my camper shell or in a tent. So, as I hadn't really had that in mind I was surprised to find how light it was and how small it stowed away. It's as light as a feather when it is on you. You barely know its there. One night it was a little too warm outside so I kept my feet outside and just laid the quilt over me. It is so light it slid off me during the night, so I put my feet back in and just shoved them through the hole in the bottom and I didn't get too hot. I like the bag I'm not sure I would purchase another one for my type of use. If I was backpacking I would definitely get one for that. All in all though I think it will work out. The quality of the bag is second to none and I wouldn't worry about keeping warm in 30 degree weather with it. Nice piece of work.
