If someone who has no idea about down quilts stumbles upon this sale, what should they buy for Alberta fall hunting? I've read for quilts you usually want the long/wide to have as much quilt possible to wrap up in and eliminate drafts.
Quilts have snaps at the top and a footbox so its not exactly like a blanket. But yes size a bit on the generous size to be safe. I have no idea what kind of temps you are expecting in Alberta so check that.
Another tip is to get one of the warm sleeping hats if they still make them. I like mine.
I think I have the Enigma. Follow the size guidelines. If in down size up. Get it warm enough for your expected temps and maybe a tad extra. Get a warm hat. Other than that don't overthink it. They work.
The synthetic insulation works. I did use a synthetic quilt on the Colorado Trail and it was nice not having to worry about getting it damp. But other than that down is lighter for the same warmth, more compressible and lasts longer. So over all a better investment for most people. A compromise is a dawn quilt that it rated for 10 degrees colder than what you expect. It will weigh roughly what a synthetic quilt quilt would for the expected temperature and have some wiggle room if it gets damp and loses a bit of loft. In other words for 20 degrees pack a 10 degree down quilt.
