Hi lads/lasses just been looking at the Hennessy hammocks and they use a rope from the hammock instead of a webbing...does anyone no were I can purchase this from..I've looked on there website but couldn't find any replacement...or does anyone no what the material is so I could buy something similar..I have found some 3 mm suspending cord with a breaking strain of 160 kg (350lbs ) but on other hammock gourds it says need at least 1200 lb breaking strain due to % angle of the hammock creating more weight lbs
