Hobbes, I am getting on toward geezerhood, and ultralight is the means necessary for me to succeed in trips. So I am very interested in your setup. I just purchased an Ursack "all white" and aluminum liner to lighten the bear safety setup.

There is an ultralight thread, maybe you could post there:

What is your sleeping setup -- mattress, quilt, etc. And how do you successfully keep covered using the quilt?

What do you use for rain protection: tent, parka, etc?
