Rusty and others, how have your jackets held up?
I recently got one and have been impressed with the combination of breathability, water resistance, and air permeability. But I've heard it is also easily abraded, pills, wets out in the presence of body oils, etc. Perhaps the tyvek in these coveralls is different than the 1443r that some mention, less prone to durability issues? According to one post above, it has a higher HH, so perhaps it is a thicker version?
