LifestylesIt's a alternative color/strip on the hammock's body. Many companies like ENO also do this.
To clear anything up: This hammock is just the cloth body with bag and cabiners to hook up to. It does not come with a bug net, cover (which none have), tarp and anything else. If you're hooking up to trees, please get tree straps or tree huggers to protect the trees--not rope. The ENO Straps you can add to this are good (sold out) so get some ENO Atlas straps somewhere.
As for if this hammock is a good deal: I've never heard of the company, but you can get many like this for around the same price. As someone else has pointed out, you can get Yukon hammocks (which would be about the same) for a pretty good value on woot.
