If you're looking for good protection and versatility in a lightweight package, the Hennessy Ultralite Backpacker Asym Zip is a fantastic option. It was one of the only hammocks in our review that, without an additional upgrade, comes with a rain fly and suspension. The only other model with this feature was the other Hennessy we tested, the Hennessy Expedition Asym Zip, which is a heavier, burlier version of this hammock.
The Ultralite Backpacker is a well-executed marriage of decently lightweight materials, solid construction, and backcountry-ready features. It was the most comfortable of all the models we tested that claim to be ultralight. It's also heavier than those models, which is a definite theme; the more material and dimensions offered, even just a few inches, the more comfort you generally have also.
This hammock has a noticeably steeper learning curve than pretty much all the other models we tested, and it took us longer to get pitched and get comfortable. But for those that don't mind a little practice and enjoy the process of tweaking their rig, this is a great hammock in all respects.
