The one thing I know is that I will not buy another travelpro or tumi bag after my recent experiences with them. My travelpro crew5 rolling wardrobe sucks, and has already burst a few seams after 6 trips. My Tumi T tech duffel carry-on has also burst a seam at the zipper after 4 trips. In contrast, my cheap 100 dollar kirkland 22 carry on is in perfect shape after 50+ trips. I have dragged that bag over cobble stones, overloaded it beyond belief, and have checked it many times. It still looks good, rolls well, and I have had no issues with it.
