http://www.slinglight.com/ I carried this for years until I decided any chair was too heavy. Now I carry two sections of a z-rest and fold them the wrong direction for my tail end--and then lean back on my pack. This is nice year round for insulation and padding. At night the z-rest goes under my legs and feet as I have a very short pad. When cooking it is nice for my knees on rocky ground. It also makes an acceptable cozy for zip bags.
