RE: Hammock Camping LONG - Re: Oh Boy, Cold Wars II, winding up!
MessageDave, your idea of a 3-strip hammock has some potential problems to overcome. First, sewed seams in lightweight fabrics are prone to tear out--when loaded, the sewing thread itself cuts the threads of the fabric and thus perforates the fabric which then tears. Of course using stronger fabrics might prevent tearing, but stronger fabric means a heavier hammock. I recommend 1.9oz/yd2 ripstop nylon for my hammocks, but for safety they should not have sewed seams under load. The next problem is even more serious.Any sewed seam in the hammock fabric will greatly affect the stretch of the fabric--the sewed seams stretch much less than the remainder of the fabric. Thus sewed seams create ridges of tighter fabric when under load and this results in uncomfortable areas--lying on or across one of these sewed seams would not be comfortable. In addition, a hammock made from two different fabrics will exhibit different stretch in each fabric--again creating uncomfortable support.You might still make your 3-strip idea as an outter shell that surrounds the hammock without taking any of the load--this may work as you hoped; worth considering. Thanks for the idea....Ed-----Original Message-----Thank you very much for your lengthy and clear explanation.

I think I understand it all but am not convinced that the forced
convection does not force cold air at least partway into the foam,
causing the loss of some of the insulating value of the closed-cell
I have to get out and experiment.
I did not properly describe my alternative hammock idea. It is a
single layer hammock. The material used to make the hammock consists
of three parallel strips of material. Two strips of windproof
material with a strip of uncoated material in between, sort of like
two red stripes on the flag with a white stripe in between.
Since the stripes go from end to end it seems that the strength of
the hammock would not be compromised. The stripes would of course be
sewn together. The purpose is to have windproof material along the
sides and breathable material below (to control condensation).
Does this idea make any sense to anybody.
Thanks for any feedback. --David
