So I'm looking at a Sierra Designs "Wicked Light" 45 degree bag as a summer bag/topquilt and was curious if anyone had used or had experience with it. I don't think they're made anymore in the down version (this one's 800 F.P. down). I think it can be unzipped to open up flat like a blanket or zip just the feet.
Has anyone used one? How's the shell material? Would you buy it again?
