We purchased a set of these bags in 2013 (the checked size and the carry-on size) and after really liking them, we purchased another set (carry-on and checked) in 2014 - different colors of course. We love these bags. The set are light, durable, compliant world wide with checked and carry-on restrictions. In fact, unexpanded, we can load the checked ones to the max and it will not exceed 50#.  The checked and carryon train behind one another perfectly and make them ideal for traveling overseas.

And they have traveled from Venice to Singapore, to Canada, South America and the UK, and all over the states. I've had Eagle Creek, American Tourister, Samsonite, etc., but we really, really like this luggage.

They do have a lifetime warranty, and the reason for this review is to laud the company for honoring their lifetime warranty and their customer service. In 2017 the expanding zipper on the 2014 bronze carry-on pulled loose and was lost. (Some airlines will not let you carry-on if you expand your carry-on.)  I almost simply ordered a new one when I looked into the warranty. After finding out it was lifetime, I contacted the company - fully expecting the run around and I was fully prepared to purchase another because we like them so much.

But after contacting the company and sending in photos of the damage, and waiting a few weeks, they simply sent us a new one - a different color of course (in Turquoise)  - but we aren't fancy travelers - and we like bright colors.

Therefore we can highly recommend these bags and this company from personal and practical experience.
