The Best Carry-On Luggage

Aer’s Travel Pack 3 is about as close to a travel-bag Swiss army knife as you can get. It’s a practically indestructible backpack made of 1680-denier ballistic nylon! It’s a sophisticated briefcase with a handle! It’s a tech organizer and a laptop bag and a suitcase! Though it might be over-engineered for some (“almost too much bag,” according to my husband), the Travel Pack has a sleek, unisex design (available in black, gray, navy, or olive) and utility that make it usable for everything from day-to-day work to business trips to international backpacking.

There’s a roomy, clamshell-style main compartment that fits shoes and about two outfits, or more with a couple of packing cubes, plus a separate divided laptop compartment for two computers. The front unzips to reveal two rows of pockets reminiscent of a miniature over-the-door shoe organizer, perfect for pens, power cords, snacks, or notepads. There are compression straps on both sides to cinch it down to a more manageable size. It should be noted that even when not compressed, the 21.5 x 13-inch profile is still small enough to be stuffed under an airplane seat. Both main compartments have zippers that can accommodate a lock, and a loop on the bag allows it to fit sideways over a suitcase handle. The only detractor is that the water bottle holder is bizarrely small, even when unzipped to its full capacity. It barely fits a 40-ounce ThermoFlask, and the included magnetic strap won’t even fit halfway around it. As long as you don’t get thirsty, this is a pretty solid bag that I think most people would be happy with. —Kat Merck

★ Alternative: I recently took Travelpro’s Altitude travel backpack ($280) on a work trip. I loved the full-access, flat-top opening, which saves space in a small hotel room. I also loved that it has structure, so you can pack it like a suitcase, and it’s expandable so you can bring home a large book or a library souvenir T-shirt if you really want to.
