I slept out in my Clark NA two nights in Tioga County, PA this week. Tuesdays temp when I woke (06:10 or so after a good night’s sleep) was 27 degrees. I used my zero degree synthetic bag, a blue Wal-Mart pad (inside the hammock), and had no ‘insulation’ in the Clark’s bottom pockets (just my boots). I slept in 100% polyester long john bottoms, and a fleece long sleeve top, with a cap. I even left one side with only the bug screen zipped, and only zipped the ‘weather shield’ on the windward side.
I slept very well and was never cold. This was its first cold weather test. My three friends that slept in the cabin thought I was nuts, but I’m sure I was more comfortable than on their old pull out couch.
I’ve read much about hammocks being too cold (on hunting forums), but I essentially left my screen door open in 27 degrees and was OK. I’m sure if I zipped the weather shield on both sides, I could have taken this sleeping system to lower temps. A better pad would likely help some also.
Now I still have to perfect my set up to assure the rig is rain and wind proof. I already know many of you others have done this. I just haven’t perfected a system yet.
