Last year I bought my first quilt, a 20F EE Enigma (850 fill duck down, reg, wide) and I love it. I chose the Enigma over the Revelation to reduce the fiddle factor and weight, and because I mostly hike in the mountains where it’s cool enough at night that there’s no need to open up the foot box. There’s more technique required to maximize warmth with a quilt, but it’s worth the weight savings over a comparable mummy bad IMHO.
The EE straps work great, although I did modify one of the straps, so that both of them now wrap around the sleeping pad – just my personal preference (and a very easy mod). By default, one strap wraps the whole way around the pad, and the other simply joins one side of the quilt to the other. I find the straps useful in the 40’s and lower, either with one side of the quilt attached only for a blanket effect, or both sides attached if it’s cooler. I believe that goose down can be requested instead of duck for some down weights, but I’ve noticed no smell with the duck down.
As a side sleeper, I ordered the wide and was glad I did. I can snug the quilt within 6 to 12 inches of both sides touching, which eliminates drafts quite well and still provides enough room. If you email EE with our sleep preferences and shoulder girth, they can recommend a Wide or Regular width to you. At 5’8″, the regular length is perfectly fine for me.
One does have to tweak the straps and fine tune the setup to minimize drafts and maximize warmth. The strap’s placement on the sleeping pad is one key parameter, and also the distance between each placement (if both wrap around the pad like mine). Another important factor is how tight the straps are (how open the quilt is).
Head insulation is very important also with a quilt. For me, a down or synthetic hood/balaclava is a necessary accessory when sleeping in cooler conditions (30’s or lower).
