This right there. This anon is mein nigga.
Snugpak Jungle in summer, warmer days. Combined with tarp and even when I sleep on the ground I never had issues with the insects. During really hot nights, I just use hammock. No tickjew at all. During the winter or shitty weather, I just use Jungle bivvy with a Helikon Swagman Roll poncho, which also works as a liner to the bivvy. If I use it with a z-lite I can sleep in hammock even if it is cold as fuck. With this combination I can pretty much sleep outside all year long, with no danger of bugs. It also saves space instead of huge as fuck winter bivvy.
So in the end, it's:>Jungle bivvy>Swagman roll poncho>Tarp>hammock
And I usually carry regular poncho as well, so you can have extra layer against the weather or if anything would happen to the tarp. Swagman roll can also work as a poncho (you can even snap it to regular poncho if you buy from same company) and works better than most winter jackets (pic related). I'm pretty proud about this combo, never had any issues with it.
