Head straight for security.

Nothing derails a vacation like the airline losing your luggage, but you also don't want to end up severely short on supplies just because you wanted to avoid checking a bag. Thule has a travel solution for you in the form of the Subterra 40L Carry-On Bag. It's designed to fit in an overhead bin while maximizing space so you can take advantage of every allowable square inch of space.

A mesh divider in the middle keeps your clean and dirty clothes separated as the trip goes on, and the removable laptop sleeve keeps your computer within easy reach during long flights. Stowable straps give you the option to carry it as a shoulder bag or a backpack for easy toting as you make your way around foreign cities. Thule also added a pass-through sleeve on the back panel that lets you stack this bag on the handle of your rolling luggage when you have a lot of gear to haul.

  • Stowable straps let you carry it as backpack or shoulder bag

  • Familiarity: I've used it once or twice and have initial impressions

Perfection is the one word that best describes this carry on!
The bag not only provides enough space to pack for few days but it also has all the pockets and extra messenger bag to organize all you electronic devices and documents. It is also such a lightweight. I couldn’t be happier with my purchase.

Thule is killing it with their bags!!

    Just set myself us with an entire thule set! Thug's bags are super durable. strong structure, durable back pack straps. This bag can be used for so much and it comes in handy!!! My go to travel bag. I searched all over to find the best bags on the market for travel and Thule is it! Got the big one roller, the smaller roller version, this one, and the duffles.
