I was anticipating biners as well after watching the videos. Not a big deal, went to my local outfitters picked a couple up for 6bucks a piece.
You can use the hamock without, sure. But it sucks, MUCH easier to just go get a couple biners. I tried savin' the weight of the biners once I saw it didn't come with the, but it wasn't worth the hassle everytime you setup and take down.
