So I'm looking at getting a quilt from EE to supplement my Marmot Helium 15 degree bag for my thru hike next year. I'm thinking the Helium will be pointless to carry, as it will be too hot to actually use at a certain point on the trail. I'm trying to decide if a 40 degree down quilt would fit the bill when summertime hits. Also I need a good summertime bag for home as well and I think that temperature range would work well. What do you all think? Anyone have any experience with a 40 degree Enlightened Equipment Revelation? Thanks!
