Hardshell luggage is a great choice for traveling because it's durable, lightweight, and better equipped to protect your belongings. When shopping for the best hardshell carry-on luggage, there are a few key factors to keep in mind.
First, you'll want to know what size luggage to look for. Size restrictions vary widely across airlines — the most common carry-on size restrictions among U.S. airlines are 22 by 14 by 9 inches, but international carriers are often less generous. Be sure to consult the airline you'll be flying with, and before you buy any carry-on, double-check that the dimensions listed include the wheels and handle (sometimes they don't!).
You'll also want to make sure your luggage is made from strong materials. Polycarbonate variations are usually best because they're durable without being heavy, which means you can pack more while still complying with the airline's weight restrictions. It's also important to have a sturdy handle (aluminum is typically the way to go) and stable, spinner-style wheels that allow you to glide in any direction (as opposed to roller-style wheels, which are less agile).
To help you out, I've put together a list of the best hardshell carry-on luggage available on Amazon. All of my picks feature sturdy spinner wheels and adhere to the most common restrictions for U.S. airlines. Read on to find the carry-on that's best for you.
