I got a Hennessy Explorer Ultralite A-Sym in 2003. I have over 5,000 hiking miles with it, and well over 4 years sleeping in it. I have enough faith in it, that at this moment it's getting a well deserved make over at 2QZQ. I'm having the Mod 4 put on it.
I baby my gear, not a rip or tear in it at all. My weight has gone from 147 to 300lbs over the last 9 years. I have 3 other hammocks, but my HH will be my go to hammock when I hike the AT again in 2014.
Their CS has always been fast to respond and always fair as well.
