The Kammock Python straps are a bit on the heavy side (a pair weighs 12 ounces), but if weight is not an issue they work great. They are very simple to set up and very easy to adjust your hammock to the correct setting. Each strap is two pieces that have been sewn together making small loops every few inches. If your hammock has carabiners on the ends (such as ENO or Kammock) then you simply clip the carabiner into the appropriate loop. On the other end is a single loop and a single section that goes around the tree and feeds through the loop which attachés the python to the tree. My wife really likes the ease of setup as she doesn't have to tie any knots and can have her hammock set up very quickly.

Here is a link with pictures illustrating on how to use them.
