Okay, the poncho liner wins. Benjammin, I've drooled over that RiverWest(?) stuff since the first time you mentioned them, but I think it'd be overkill. I have a military poncho already, combining it with the liner makes the most sense.

The 60-70's are nighttime temps, I just want something I can throw over me while I sleep. Judging from my normal body temp levels, I think I'd be comfortable with this setup down into the low 50's inside the bivy.

Thanks all!

p.s. This is the one I'm getting, probably digital camo.
