I have the warbonnet blackbird double layer 1.1 because I am 6' 6'' 230 lbs so i need a little support and what not. For a late March, early April start from Springer, I will be sleeping with the blackbird, a 20 degree sleeping bag, a insulated pad that fits in a pocket within the hammock so it does not move, thermal underwear for bottom and top, a hat and gloves and rain tarp. I sleep very hot. Am I really going to be cold ever if I dont have an expensive under guilt and top quilt etc?
