I have an ENO setup, BUT I am not a master Hammock guy.

Right now I tend to camp in the late summer until late fall. This lead to cooler (COLD) nights and sometimes cold rain. Without extra stuff, this is not hammock weather.

IHMO, Hammock is probably the best solution for summer camping. You know those nights when it is still 80+ degrees and high humidity. Those nights when you sweat the night away. I wish I had a hammock when I use to camp and boat in June, July, August.

To answer your question:
1. Get a bug net. ENO makes a pretty good one.
2. I have an after market rain fly that is not ENO. The ENO just covers the hammock. IF the wind and rain kick up, there is a potential to get wet. ENO should have made their fly to have 6-12 inches hang over on both ends to keep the person dry.

Hope this helps.
