Didn't buy from massdrop, but I do own one of these Hammocks. As far as Hammocks go, the Ultimate Double Hammock is very large, easily accommodating two average sized people (with room to spare). The nylon is very high quality; I found no rips or loose seams in mine even after 3 months of extensive use. The Titan straps are very secure, and make hanging the hammock incredibly easy. If you are on a budget, you can skip them and use rope instead, however the straps streamline the process exponentially.
Compared to the ever popular Eno Double Nest Hammock, the Ultimate Hammock is
-Just as Durable and well made, it would seem
-Comes with equivalent straps (the titan straps are very similar to Eno's Atlas Straps. I would use both interchangeably)
I would recommend this hammock without a second thought. The only issue I would be able to think of is for Ultralight Backpackers, who would prefer a smaller, single hammock, or who would like to purchase a bug net for their hammock (some bug nets may not cover the entire Ultimate Hammock Double) I hope this helps you all
