After 4 years and probably 300 long haul US domestic segments, my trusty Tumi 6-suiter is about to bite the dust. It's one of those big foldover garment bags with a retractable handle. The ballistic nylon is starting to fray, a couple of the zippers have problems, and the bag is starting to come apart.

How long would you expect a top-of-the-line bag to last? Did the bag serve me well, or did it give up the ghost too early?

And what should I replace it with? Recommendations, please.
