Edit: Title should say "western flyer, two years in".
I've been using my WF for 2 years. I have been using the bag about twice a month for the two years I've owned it. It's been on a few motorcycle rides in the rain, and thrown about in the backseat of my car, and many camping trips.
As you can see, it is like new, except for some of the paint wearing off on the zippers.

this is exactly how I packed everything (ie: not too carefully. The bag has enough structure that you don't need packing cubes (although they are still useful for keeping things organized.)
that's 8 shirts, 2 sweaters, 3 pants, scarf, toiletries, underthings, jewelry in a tb pouch.
