The cool thing is that it's your own individual tent, bug screen, rain fly and bed (also can be used as a camp chair) and is easy to pack and carry (weight is important when you're out there!). With the "snakeskins" (a kind of sleeve that they easily roll into), you can even hook it on the outside of your pack. They're supposed to be very comfortable to sleep on (pressure points are murder after a hard day of hiking).
You can check out the specs on this model here http://hennessyhammock.com/catalog/#hammock (scroll down to our model). While you're there, check out the info on hammock camping. Once it has arrived and we learn how to use it, I'll report back with some pics!
