Sorry if this is the wrong thread as it may borderline on technique.
While I've had several florless shelters before this will be my first tarp bivy setup.
So I know there's been discussions on using mylar bivys or heat sheets for the summer, but let's say a bivy is a given: will be used under tarp and provide bug protection. My concern is with a 50*F night, the bivy with my 30 bag will be a sweat factory.
What do others do for this situation? I've wondered about just putting more clothes on at night or my down jacket, or maybe a sleeping bad liner? I'm not a super hot sleeper, but the humidity could still be a problem on summer nights.
Thoughts? Any detail I need to add?
