As far as how small it packs down, it will probably will be about the same as any other quilt. Also it depends on what size quilt you purchase and if it is overstuffed. The quilts do not come with a stuff sack yet, but when I emailed him, he mentioned he will start including them in 2013. Also, he mentioned that if I ask him for one with my order now he will include one. I bought his Revelation X 20 degree in the largest size and overstuffed and it is a very good quilt. It is also very multi-functional in that I can use it as a top or bottom quilt and it has loops to secure to a pad when going to ground. I asked for a stuff sack and he sent me a prototype waterproof sack with a roll top. it is very nice, though I like to compress all my quilts in a different compression sack (with my pillow, hat, socks, etc.).
I hope I did not step on his toes by mentioning the extra stuff sack. His work is very high quality and the price is very reasonable, and I am currently saving to purchase a 40 degree quilt for next summer.
