My hammock will be a summer rig for the foreseeable future. I will be using it for northern Minnesota fishing trips. Summer temps up there will get down to the mid forties at times. I have a 40 degree mummy bag. I slept in my GT UL last year an I figured out the hard way that I needed some insulation. I used my 3/4 thermarest but it was not very comfortable. I am going to have to try some things out. Maybe I will try a DIY UQ. I like the size of that 3/4 pad it is small. I wish I could try out a HHSS. I had a Potomac bought from another forum member but it got lost in the mail over a month ago, so I am writing that off. My system will be used primarily on canoe trip or car camping until my son gets old enough to carry his own gear. Size and weight are not the biggest concerns at this point.
