I have rather mixed, though generally favorable, feelings about it. The claimed comfort rating at -7°C sounds great, but I have serious doubts whether that is actually achievable. I tested it at roughly 1–3 degrees and naively expected it to provide noticeable warmth from underneath, but in fact that was exactly where I felt the cold more than from above. I still intend to test it again, because it is possible that I did something wrong during installation or adjustment, or perhaps it was pressing too hard against my back... hard to say. One thing is certain: it works to some extent, because the Swagman Roll I had used before was already not coping at +6°C, and on top I had a Zenbivy quilt with a comfort rating of +10°C (+4 limit), which I actually perceived as warm and had to vent from underneath. What I really like is that you can cinch not only the shorter sides but also the longer edges, which makes it fit the shape of the hammock better. The manufacturer did not describe this, and I have not yet come across a similar solution anywhere else. On the downside, for me it could be a bit loftier; I have the impression that the insulation is packed too tightly and no matter how much I try to fluff it up, it does not gain more volume.
