How to Live a One Bag Life

GET ORGANIZED

Don’t worry about your backpack being a black hole. We designed pockets, sleeves and clips that help keep your everyday items organized and in place no matter where you go.

STAY FLEXIBLE

Not sure about staying in town after your business trip ends? Unzip, expand and pack our hidden suitcase compartment with a change of clothes and be spontaneous.

BE READY FOR ANYTHING

Inspired by tailored clothing fabrics, our custom-designed, two-toned, water-resistant fabric is as much at home at a meeting with your boss as it is at drinks with your friends.

KEEP CONNECTED

Feel free to carry your laptop day and night. We designed our padded computer pocket to be easily accessible and close to your back for carrying comfort.

WEAR A BACKPACK BUT DON’T LOOK LIKE A HIKER

Our zip-away side water bottle pocket keeps your drink handy and your bag neat.

BE PREPARED

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

HAVE FUN

Our custom-designed lining brightens up your day and ensures things never get lost in your bag.
