It got down to 27 degrees here lastnight and thismorning.
I am sold on these 2 bags, the Intermeadiate and the Extreme.
Not having to mess with all the extras stuff, just a simple hanging rig, Hammock, sleeping bag and a tarp.
So far I have used a Hennessy and the Grand Trunk UL with these bags.
It's all in the insulation, be it a quilt setup or bad a$$ sleeping bag.
