    Double layer hammock effectiveness?

    How effective is a double layer hammock at keeping a pad from moving during the night? Is the difference really noticeable?

    I'd say it is a definite improvement. I only used a double layer for a short time (before moving to underquilts) but I think it was a massive improvement over struggling to keep the pad situated in a single layer.

    The regret that I have is that I spent money on a double layer to enhance my pad experience, when pads are just not a long-term viable solution for insulation. I always had condensation with pads, but the lower the temps, the worse the condensation. My last night with a pad was at 22* F, and I was absolutely soaked in condensation and so was my son. And if you're dumb enough to "supplement" your insulation by layering up with down jackets, long johns, etc., you'll wake up with everything soaked in sweat and condensation. Not a great way to greet a 22* F morning! That was my last night with a pad before buying an underquilt.

    Of course, there are pad aficionados who claim that they NEVER get condensation. I don't even see how that's possible, but to each their own.

    Are you all sure you aint pissing in your sleep ? lol
    I quickly sewed up an UQ when I got my 1st HH hammock, I tried a sleeping bag and layers but was cold.
    I have 4-5 UQs for my various hammocks, I bought a 2nd hand HH Jungle that came with a pad for between the layers. I made an UQ for it when I got it.
    On one trip I took 7 kids(teens) and I had to resort to the pad for me, No condensation,, but I was cold, a lot colder than the UQ.
    A pad is a temp or emergency thing,, till you can secure an UQ

    I don't understand why a pad in a hammock would cause more condensation than a pad on the ground (i.e., in a tent) unless the hammock is buttoned up pretty tightly, e.g. with a top cover.

    All that cold air flowing under a pad in a hammock. Convection, my friend. For your reading enjoyment:

    My 2 cents - IMHO They are very effective if you can corral them - If you have a means to slip the pad between the 2 layers it will help secure the pad better than just laying on top of it. Also if you have a way to insert the pad between the layers and there is a "channel" that is designed to be slightly larger than the pad - the pad will not go anywhere - You can also try to sew elastic bands on it - sew a band that goes from top left to top right and slip the band over the hammock - do this top and bottom and see if that will stop it from shifting so bad.

    Best solution is to create the internal "channel" for the pad to go into if you can IMHO

    Technically speaking, heat lost to wind is primarily conduction. Convection is air movement primarily driven by gravity, warmer air rising. That said, I get what you're getting at and don't want to start a physics debate.

    I guess the pad can be cooled so much that the dew point is reached on the top surface. That and moisture is trapped between the skin and the impermeable pad.
