Hug amount of loft.
No need for a bivy.
Some epiphany quilts had problems with down shifting but this 10 degree has so much down it is not a problem with the karo baffles. The cuben shell does not breath so in order to avoid claminess don't wear layers with this quilt on your legs, a jacket is fine to keep out drafts and I did wear down booties because the footbox cinches up.
recommended for cold sleepers.
I put 3 pieces of tyvek tape about the size of a thumb nail in 3 spots where I saw down poking out at a stress point by the straps. I'm had this happen with other epiphany quilts and usually a piece of tape and you are good to go.
This is a different epiphany bag but it gives you an idea of the loft.
