I always have a little anxiety when I check a suitcase for a flight. What if it gets damaged, or worse—lost?

Eagle Creek is taking on both challenges with its new Caldera line of suitcases. Thanks to a polycarbonate back shell and a body made of recycled Cordura poly that is tear-, abrasion-, and water-resistant, the bags are lightweight but tough.

They’re also full of smart details: reflective, water-resistant zippers; a proprietary system that keeps the handle from being crushed; personalizable rubber side handles; side straps with aluminum hardware that can be tucked away; and a “coat keeper” that allows you to secure your coat to the top of the bag as you’re rolling through the airport.

But the thing that really got me excited about the Caldera line is TripSync. Each bag in the Caldera line is equipped with an NFC chip that allows you to report your bag if it’s lost and tracks your trips for a cool digital reminder of where you've been.

Eagle Creek sent me the 100-liter wheeled duffel to test, and I brought it along with me on a trip to Israel. I wasn’t able to check out TripSync (which was still in beta at the time of my trip) but here’s how it works: First, if your phone requires it, download an app that will read the NFC chip. Then, hold your phone near the luggage tag, which will launch a video describing the features of your bag and how to care for it. (There’s also a handy diagram that will tell you which Eagle Creek packing cubes you need, and the way to orient them, to get the most space out of your bag.)

After the video, you’ll sign up for an account. Don’t forget to register your bag—it’s the only way you can report it as lost if it goes missing. You may also need to adjust your settings to allow TripSync to get your location so it can accurately track your travel.

Before you check your bag or hop on the plane, scan your bag and make sure you’re logged in, then click “start trip.” After that, you’ll need to scan your bag and click “add stop” or “end trip” to log your travels. (These steps are important—the bag isn’t actively being tracked by GPS, so trip length is based on the points you log and determined by “the most direct path between the points,” according to Eagle Creek’s website. “The total miles traveled between each point you create become your total miles traveled for that one trip.”)

If you need to report your bag lost, you do so by logging in and clicking the “report lost” button. When someone finds the bag, all they need to do is scan it with their phone to contact you; none of your information will be revealed. When your bag is back in your hands, you can mark it as found.

If your bag gets lost, whoever finds it just has to tap their smartphone on the ID tag and you'll be contacted. Eagle Creek

Though I wasn’t able to try TripSync, I was still impressed by the physical features of the bag. The bag is durable as promised, and spacious—I had plenty of room for everything I wanted to bring, with space to spare for souvenirs. (The suitcase is also expandable via a zipper, but I didn’t have to use that feature this time.) Thanks to the sturdy handle and rugged wheels, the bag handled great both empty and when it was fully loaded, both on smooth streets and uneven terrain. And as a person who struggles with what to do with her coat when wheeling all of her luggage through the airport, I found the coat keeper to be especially helpful. I can’t wait to take the bag on another trip to try out TripSync for myself.

If you’re not in the market for a carry-on or checked suitcase, Eagle Creek also has a Caldera backpack as well as a convertible bag that can be both worn as a backpack and rolled like a traditional carry-on suitcase.

The bags come in black and green; they start at $279 for the backpack and go up to $569 for the four-wheeled 100L model. You can buy them on EagleCreek.com.
