User Review: Eagles Nest Outfitters DoubleNest
I used it for the first time on a backpacking trip in mid September of this year. It was unbelievably comfortable. The temperature at night dropped considerably, and even with a sleeping pad, I got very cold in my underrated sleeping bag.
My backside was fine, but I was very cold everywhere else. I simply lined it with a space blanket (the good kind, about $14 at REI), and I was fine.
I have never slept as well on the ground as I did in my hammock, once I got warm. From now on, I'm going with a hammock. I also have the Bug Net, and the Dry Fly rain tarp.
All total, it doesn't seem to save anything in weight, or packing size, over a tent. But, the comfort level is no comparison.
