HOW TO LIVE A ONE BAG LIFE

OFFICE, GYM, AND TRAVEL IN ONE BAG

Everyday organization and large carrying capacity for whatever the day holds.

ORGANIZED FOR WORK

Protective fleece-lined tablet pocket, mesh zip organization pockets, & elastic loops for cords and pens.

EXPAND YOUR HORIZONS

Our patent-pending, hidden expansion compartment is the secret sauce that makes the Convertible Duffel perfect for living a One Bag Life. Simply unzip and expand the main compartment to get over 67% more carrying capacity. Unexpanded: 24 Liters. Expanded: 40 Liters.

SWITCH IT UP

Backpack or Duffel? The choice is yours. When you want to change from a backpack to a duffel bag, simply unclip the shoulder straps, and tuck them away in the zip back panel pocket, attach the shoulder strap, and voilà, a great duffel!

BE PREPARED

It should never happen, but if that flight attendant makes you check your Convertible Duffel, don’t worry about your straps getting caught on the luggage carousel. Simply unclip your straps and stow them out of the way in the back panel pocket.

STAY CONNECTED

Use the Convertible Duffel’s padded side computer pocket to always keep your laptop with you. The pocket fits 15” laptops (measured diagonally) and its suspended bottom helps keep your computer safely off the floor whenever you put your bag down.

BRING YOUR SHADES

The fleece-lined, sunglasses pocket is designed for easy access and protection. And there’s a bonus pocket behind it for other items (phone anyone?) that you need at a minute’s notice.

DON’T LOOK LIKE A HIKER

Only you will know that the sleek, hidden, zip side water bottle pocket holds your 25 oz S'well™/ 32 oz Hydro Flask™ bottles/ 20 oz Knack Insulated bottle.

BE DISCREET

We’d love to tell you the location of the secret zip pocket for valuables, but then it wouldn’t be a secret.

STAY FLEXIBLE

Our adjustable sternum strap does a great job of distributing weight when you’re in backpack mode. But if you prefer a cleaner look, the strap unhooks for easy removal.

BE COMPATIBLE

Sometimes, your trips require a big piece of wheeled luggage. Don’t worry, it’s easy to bring your Convertible Duffel along too. Our hidden trolley sleeve lets you slip your Duffel over the handle of almost all sizes of wheeled luggage.

LOCK ON

Keep everything secure during your journeys with lockable zippers on the main compartment. (Lock not included)

STAY DRY

While we don’t recommend swimming with your Convertible Duffel, our specially coated fabric and reverse coil zippers help keep your belongings dry in all types of weather.

SMELL FRESH

Our custom-designed lining has a special antimicrobial treatment that helps to keep your Convertible Duffel fresh even when it’s filled with dirty or sweaty clothes.

I liked the multiple ways to carry this item, and its size will be helpful on future flights!

I love the new bag. It does everything. The only addition would be a front zipper flap to quickly access important items.
