If you are going to use a hammock, there are some diy solutions available, as well as an astounding number of custom jobs
like this. Be interested to know if anyone has experience with hammock applications for camping.
I use tents, rather than hammocks, since I often pitch in treeless environments, but there are plenty of backpackers who prefer hammocks, and there are several manufacturers - Hennessy is the most well known brand, carried by REI (along with Eno), and there are several cottage manufacturers. I believe there is a forum dedicated to hammock camping, but I have never logged on.....
