Briggs and Riley

Nothing more to say. A warranty that can't be beat, well built, yeah.... maybe a little pricy but when you realize you'll never have to replace it, it works out (two co workers have replaced their bags twice in the past year... a mix of Samsonite, TravelPro, Tumi, and Vitrinox. I have over 100K miles on my B&R this year *alone* with zero issues, and I'm forever dragging it up and down stairs rather than carrying it up and down).

the 21 NX rollaboard is a great choice.... fits in all domestic overheads and still expands when you need it (although you might have to check it then if on a crowded flight in coach).
