A guy at my local outside store showed me a potential mat to insert between the layers of a hammock, it is downfilled and inflatable to 3.5 inches. Not sure if that would be too thick, but either way it seems like a really cool mat. Packs down ridiculously small.
I was browsing the website and turns out they produce a hammock!
Anyone heard of them or from the spec's can tell me if it's anything special?
