Familiarity: I've put it through the wringer
I've had this bag tied to the back of my bike for roughly 8000 miles. I've had it through all kinds of weather, from the coldest and wettest to the hottest and most dry. It's held up incredibly well, and even fell off at 70 once. All seams and leather are intact and getting a really nice patina on them!
