Quite a few uses behind. I bought it for a hammock and it is good. The packaging size/weight in relation to the thermal value is good. At first I felt that the material was somehow thin and flimsy but it is not, it has lasted very well. I would buy it again

The product corresponds to its description. The straps that go under the sleeping pad are a bit flimsy, which is a small minus for the user experience.

Lightweight and packs into a small space, extremely versatile and recommended. But that 20F/-6C might be an exaggeration.

After using it a couple of times, it's a really good alternative to a sleeping bag! Nicely warm and blanket-like. In the middle, there are two elastic strings that can be pulled under the sleeping pad and fastened with a snap, so it stays in place better with the pad. There's also a snap fastener at the neck that you can put around your neck so it stays on better while sleeping. In my experience, there was no suffocating feeling at all. Comes with a compression bag and a larger bag for storage.
