I've had, and still have Andiamo Valoroso... same with Tumi. Both classic, well built and designed brands, always welcomed into boardrooms.

For the last thirteen years, I've transitioned to Red Oxx and Tom Bihn carry on's. Very well designed, over built, lifetime warranties, never questioned when entering business meetings, constructed to last more years than you will ever imagine. Add a Tom Bihn Absolute Strap and you're in business.

The latter two... Very highly recommended.
