An hummingbird hammock is only 14 ounces with straps. If you use a ground pad and tarp anyway, that's a very light weight penalty to sleep off the ground or take naps in. Can't beat a hammock for a camp chair.
Hummingbird Hammocks are too short for me to get comfortable. I do have a DIY hammock that is 12' long and weighs 15.27 Oz. with the tree straps and whoopie sling suspension so those types of weights aren't unreasonable for a good hammock, I just wanted to point out that most people will be much more comfortable in a longer hammock. I prefer 11' long at a minimum, 12' is better but I'm also 6'1" so that comes in to play as well. As I said before, as simple as it sounds to grab a hammock and go, there is actually quite a lot involved in getting the setup right for you to be comfortable in most any situation.
