UPDATED DESIGN In response to customer feedback, this product was updated in 2019 to be more lightweight user-friendly. Please see the updated Product Features, Images and Product Specifications. The Fortis Pro USB Carry-On has everything you need to take charge-literally and figuratively. With an integrated USB charging system, you can charge your phone without having to search for an outlet frantically. Here's how it works: there's a cord connection and dedicated battery pocket on the inside of the bag. The USB port is located on the outside of the bag, giving you access to your phone while charging. The battery is not included, but the pocket fits nearly every portable battery on the market. We even updated the design so you can remove the battery without unzipping the entire bag. Other good news: the interior compression strap features built-in packing cubes with wet/dry pockets, keeping you organized while compressing your stuff. We also included a removable laundry bag for your dirties. Even better: the Fortis Pro has four silent Hinomoto wheels-the best wheels money can buy. And because we truly care about your travel experience, we offer this premium bag without the premium markup.
