For families trooping off on a big trip, duffels deliver. Roomy and lightweight, these bags have evolved from army stuff sacks into virtual closets on wheels. The newest are adventure-ready, thanks to structured sides, go-anywhere materials, and a wealth of zippered compartments. Best of all, they're a cinch to spot in the airport pile.
