I don't think he's talking about the specific hammock. Most hammocks can be ground pitched - it's not optimal but many have sewn in bugnets and make adequate bug bivies.

My hammock, tarp and two quilts weigh about five pounds total and pack smaller than the tent setup I was using. Add a NeoAir, usable in hammock or on ground, for trips where I can anticipate the possibility of going to ground (13 oz) and leave one quilt at home (20 oz quilt, savings of 7 oz). If I spend four nights in the hammock and one on the ground, I will have gotten 32 hours of sleep for the trip. If I plan to sleep on the ground I will probably get four hours of sleep in four nights. YMMD (Your Math May Differ).
