Hey everyone! I just spent last night sleeping in my backyard in my HH experimenting for a trip in a few weeks. The temp was between 25 and 30 F. I used the HH underpad and undercover with a fairly low quality sleeping bag (550 fill goose down, 2.6 lbs total, rated to 30F). In it I wore cotton long underwear and a fleece sweater. I was cool enough that when I woke up at 2 am I decided that my warm bed was a better place to spend the rest of the night, but not cool enough that I could not have handled a night in the woods.
Anyway, that is just FYI. My real question here is how to adjust the HH rain fly, that just doesn't seem to get taut no matter what I do. The thing is, no matter how I adjust it, the center line always has looseness to it, though the sides seem to tie down just fine. Any suggestions? I didn't get wet, but with a heavy rain, I can't see this working well. What am i doing wrong?
