I bought this to match my smaller roll-on T-Tech case. This bag is too large to be carried-on and must be checked. The external material is tough black nylon woven material with lighter grey nylon (or poly?) woven accent. There is no leather in the trim except on the top and side handles which are padded. The extendable metal handle has a rubber grip and it's quite sturdy. With the push of one button it extends smoothly, and then tucks back into the bag with a zippered cover to protect it. I love the design and though it is a two wheeler, it navigates perfectly through the airport or on rough ground- even when fully loaded. The cover is extremely durable and I've not seen a single mar on it despite checking it with United several times. I expect it to last many years. The internal and external compartments are quite useful. It has a front zip compartment that is perfect for storing toiletries - so you have easy access when needed. Behind that is a small zip compartment that stores a strap with clip for 'piggy backing' other bags (useless to me) but I have taken to storing my boarding pass in there so it is at my fingertips when I check in. Behind that is a 2-4" deep zip compartment that runs the length of the bag - and I use it to store shoes so they don't get my clothes dirty. If anything gets squashed by the airlines, it will be shoes in this compartment. Inside you'll find belts that strap your clothes in place so even after customs finishes rummaging around, you can strap the piles of clothes securely in place. Inside you'll also find a (zip out) fold out board - so you can keep suits on the top folded around it and they arrive relatively unwrinkled. A great choice for a professional. I'd buy it again in a heartbeat - highly recommended. (Amazon price was quite reasonable too!)
As the proud owner of multiple Tumi products I can attest to their quality of construction and durability. As a "road warrior" traveling 40+ weeks a year I can really punish luggage and Tumi products have always held up. Th Never blue is also easy to recognize on a luggage carousel.
Tumi bags are the best in baggage. They are proven to last years, having had an original Tumi bag, I purchased the medium wheeled Mason bag for weekend getaways with my wife and it is the perfect size for both of us. If your tired of your bags falling apart, spend the money, because Tumi bags will last a lifetime.
