Your weight at 195 lbs. isn't an issue with the Nano-7. I'm usually at 225+ and hang no problem. Your height like mine is where the issue arises. IMO anyone over 5'10", maybe 6', is going to have a tough time getting anything like a traditional diagonal lay in this hammock. I have two of these hammocks for scout sons. They are great for backpacking hangs until the boys start to get on the large side. I've moved two sons into custom, cottage manufacturer, hammocks as they struggle to get a flat, diagonal lay at the 5'10" and 200+ size. Your experience may vary.
