"Most baggage isn't designed for every day usage, that's why expensive leather bags' threads come undone after 3 years. And the Polos, Samsonites, Pierre Cardins, and Delseys, said to be for frequent travelers, are in fact for travellers who travel rather infrequently; nylon, imitation nylon, and denim computer attaches included. They all get worn out quickly: Ragged, shredded, . . . zippers get jammed, wheels squeak, handles come off. Name brand, stylish, fashion forward luggage is nothing more than an overpriced compendium of horsesh!t. Dependable airline crew luggage has yet to be invented."

Can't see how these would ever give up service like a leather bag. This one though I was more thinking of as luggage and not a cockpit bag
(although I think I saw one in their range that would fit for that use as well...)
