Familiarity: I've put it through the wringer
I wear these while working. I am a biological technician and spend hours upon hours a day walking an average of over 9 miles over rough terrain, across nasty mud flats, and through thick sagebrush and cacti. These gaiters keep my pants, shoes, and socks dry on even the wettest days, and the straps that go under my boots do a perfect job and stand up to even the worst abuse by mud and me knocking and scraping it off on the edge of a concrete pad.
I haven't had the opportunity to test them against a prairie rattler, but I don't doubt they would be able to fend off the fangs of those guys, either! (Don't test that theory; this is worst case scenario.)
