I'm headed to the Boundary Waters in August, where it will be buggy. It also can be warm or chilly. I am a newbie, with a new Byers mosquito, and a ccf pad, which I plan to use with a sleeping bag in the hammock (probably). I am concerned about bugs biting through the hammock, and the colder nights. So I'm wondering if I can make a cheap and easy underlayer that will help. What if i buy some ripstop and rig it as an underlayer (no sewing, please)? Will it work, and how can i do it? This seems preferable to the extra weight of an underquilt.
