one of his ideas is great. the carrying of a couple of scarves, made of bug netting, converted into bags. They can be slipped over you, bottom and top and give you bug relief, rolled up for use as a pillow, stop the "pumping action " (his words) of your clothing, which forces your bodily-warmed air up out of your collar as you walk/work. They can be used to catch insects or seeds, as a rain-catch (sort of) used for sopping up dew or frost, as a wrap/pad for other gear. They can be stuffed with debris and sleep on one, with one over you. 1/4 lb each, that's a HELLUVA lot of utility, for very little bulk and weight.
