Some bags have been around the world, and it shows. These well-worn cases—sourced from the PopSci network—bear the scuffs and dings of adventures logged since the luggage first left the store. Start your own globe-trotting with a brand-new one, and its lifetime warranty will help it last from a gap year all the way through an Alaskan retirement cruise.

Zero Halliburton Polycarbonate Spinner

This 7.9-pound (minus stickers) case has logged more than 250,000 miles. The 21-​inch-​tall, 9-​inch-​deep body meets global carry-on standards, and two TSA-approved locks snap it shut instead of snag-prone zippers. Sam Kaplan

Timbuk2 Copilot Roller

The tight weave of this 7.6-​pounder’s nylon exterior may show the scars of many trips Down Under, but it won’t rip. Inside, a rubbery neoprene lining protects souvenirs, and an expandable pocket ­sequesters those dirty socks. Sam Kaplan

Filson Field Bag

Wax treatments over the course of 11 years made this satchel supple and water-resistant; they’ve also turned the cotton twill a darker brown than an off-the-shelf ­carry-​all. Under the heft of cameras, the leather straps softened but are still sturdy. Sam Kaplan
