Hennessy Hammocks is making a new type, one that has a side-zip, as opposed to the birth-canal like entry (as it is often referrred to). Although the bottom entry is great, some, like me, had their hammocks modified for side entry. the upsides of using a hammock are site selection (as long as you have anchor points, you have a campsite), ease of setup (once you have a system down, it typically takes about a minute), setting up out of the weather (I ALWAYS set the tarp up first, so I have a nice, dry place, out of the sun, to set up the hammock), and comfort (nothing digging in to me). Barring any camping in the winter (which I no longer really do), my tarp/hammock combo will be my main go-to for any & all overnights, so long as I can find 2 places to tie off.
