My friend who got me into hammocks- but who never comes to this site for some reason- got his a*s chewed up on rainy night in SC. I think he was in a single layer HH Expedition, but it could have been another one of his "parachute" hammocks as he calls them. But, all single layer. Also, I don't know what else he was wearing for clothing, but it was a hot summer SC night, and he was inside the netting, so probably not much. Maybe just a pair of shorts, or maybe even just his underwear, don't know. But the next morning he discovered his behind was a pincushion.
I figure bites are rare, because most people, most of the time, either have a pad, or a HHSS at least the UC part, or at least some minimal summer UQ, and if none of that most of the rest have a dbl layer hammock. Any of that naturally makes bites through the hammock virtually impossible. I suspect so would sleeping in the right clothing.
But a hot night, with minimal clothing and a single layer hammock, it might be a good idea to treat the hammock exterior with Permethrin. Although, some hammock materials resist mossies more than others, even with single layers. I have heard that rumored about the HH ULBP and Explorer UL, for example. I'd have to hear more confirmation of the rumor though, before I would risk it. I don't need no West Nile Fever!
But in a hammock, all you need out of a pad is insulation. You do not need cushioning. And a much thinner, lighter and cheaper CCF pad will insulate as well as a thicker, heavier inflatable. And what if it is really warm(lows guaranteed above 70-75), how much pad do you need? NADA! So under the right circumstances, we who need thick inflatable pads on the ground can now go to zero pad weight. Assuming you are willing to go without a pad for emergency ground use or a sit by the fire pad. Under all circumstances, I can get by with a much lighter pad. Or, maybe no pad other than sit pad and just 6-8 oz worth of IX UQ!
So what does that outlook do to weight and volume and maybe even cost comparisons?
But anyway Luisdent, basically if you can use it on the ground you can use it in a hammock, with a bit of learning curve. If you are a tarp/bivy type of guy, Just think in terms of the tarp, pad and top quilt are the same( unless you are using a full bag, in which case going to just a TQ will again save you some weight. TQs cover you better in hammocks than on the ground). You will just use all of those in your hammock. Think of the hammock as replacing the bivy. Think of it as a bivy that is hung from the trees off of the ground. And if you are forced to ground, you will just use that bivy(hammock) on the ground, still under the tarp and still on the pad.
