I've had a hard time researching this because most references to winter hammocking don't apply to the Canadian winter. If anyone knows of such a thread, please point it to me:
I want to be warm at -22f/-30c temps (preferably higher, but this is the minimum).
I currently have a HH+SS(overcover, undercover, underpad) and will purchase something like a -30c/-22f sleeping bag with wind block, a silk liner for the bag, and a large tarp.
At first, I thought that the underpad covered with a space blanket would be enough for the hammock to be comparable to a tent+pad. Some more research suggests that this is not the case. Now, I'm considering the options, but the KickAssQuilts are rated at +30f, the JRB Winter Nest at 0-10f, the peapod at 20f. I could layer several pads together, but I can't afford trial and error because most of my time is taken up by university.
At this point, I'm wondering if hammocking in this weather is possible, and if I should just go to the ground instead.
