Congratulations on yet another researched, clear,and integrated
article that helps to balance the trend away from hype, faddishness,
and heat without light.
Although you all have discussed this indirectly here and elsewhere,
could you consider sharing with people an aspect of misunderstanding
that pervades the sale of millions of dollars worth of this type of
raingear, i.e., that when it is raining and the relative humidity is
100 per cent, nothing breathes. The utility of insulation that keeps
insulating is what counts in these conditions, as you keep pointing
out. Yet many of my fellow hikers in the Northeast keep spending
megabucks on this rainwear, and pop it on over their down vest and
coats only to find out they are soaked and cold. However, because of
the principle of "cognitive dissonance" (the more you spend the more
you are psychologically pressured to believe it is of value), they
continue to believe in the rainwear and the down.
I have, as you all promote, use primaloft plus a poncho tarp in all
but the most exposed and high wind areas, and find that moisture
transfer, heat build up and drying time are almost always better, and
it is a double duty set up, i.e., my shelter as well. Invariably I
am looked at as a nut as they stride by with their $1000 set up,
soaked and miserable.
