HOW TO LIVE A ONE BAG LIFE - EVERY DAY

STAY CONNECTED

Use the Knack Pack’s padded side computer pocket to always keep your laptop with you. The pocket fits 17” laptops (measured diagonally) and its suspended bottom helps keep your computer safely off the floor whenever you put your bag down.

ORGANIZE THOSE CORDS

The easy access charger and battery pocket helps keep all those cords, chargers, adapters, batteries and USB sticks that you can’t live without in one neat place instead of rolling around in the bottom of your bag.

BRING YOUR SHADES

The fleece-lined, soft case sunglasses pocket is designed for easy access and protection. And there’s a bonus pocket behind it for other items you need at a minute’s notice.

HOLD THE CARDS

Feel free to throw in a bunch of business cards - there’s plenty of room in the organizer panel. Also, rest assured that your passport and wallet are safe. Our RFID blocking fabric protects your RFID chip cards from unwanted skimming.

STAY ON KEY

Our removable, easy-access key leash makes it a breeze to bring your keys with you everywhere.

CARRY IT ALL

The Knack Pack’s main compartment has two generously-sized, soft monofilament mesh, zip organization pockets. Our special mesh makes it easy to always see all the things you stuff into the pockets. If that’s not enough, there’s a protective fleece-lined pocket to keep your tablet safe and sound. Main compartment is 30 Liters.

DON’T LOOK LIKE A HIKER

Only you will know that the sleek, hidden, zip-away side water bottle pocket holds your 25 oz S'well™/ 24 oz Hydro Flask™ bottles/ 20 oz Knack Insulated bottle.

HOW TO LIVE A ONE BAG LIFE - TRAVEL

EXPAND YOUR HORIZONS

Our patent-pending, hidden expansion compartment is the secret sauce that makes Knack the perfect One Bag Life backpack. Simply unzip and expand the compartment to get over 50% more carrying capacity. Unexpanded: 30 Liters. Expanded: 46 Liters.

PACK IT IN

Not sure about staying in town after your business trip ends? Pack our patent-pending, hidden suitcase compartment with a change of clothes and live spontaneously. Packing capacity: 16 Liters.

LOCK ON

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

BE COMPATIBLE

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

STAY FLEXIBLE

Our adjustable sternum strap does a great job of distributing weight when you’ve really packed your Knack. But if you prefer a cleaner look, the strap unhooks for easy removal.

LIGHTEN YOUR LOAD

We understand, sometimes you over-pack. That’s why we added loops so you can easily add a waist strap to help distribute the weight from your shoulders to your hips. (Waist strap sold separately).

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 unclip your straps and stow them out of the way in the back panel pocket.

KEEP DRY

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

SMELL LIKE A ROSE

Our custom-designed lining brightens up your day and ensures things never get lost in your bag. And our special antimicrobial treatment helps to keep everything fresh even when you’ve packed dirty or sweaty clothes.

LOOK SHARP

Inspired by tailored clothing fabrics, Knack’s custom-designed, two-tone fabric is both lightweight and durable.

A pocket for every purpose provides a way through your pack without unpacking the whole darned thing. It’s space and weight efficient. It allows me to use for work—traveling or a day at work. Great weekender. . Exceeded my expectations.

Great bag for back to the office!

I love this bag for more than just travel!
My company has implemented a flexible work schedule which means I am in the office a few days a week and home for the rest. However along with the flexible work they have also added desk sharing called hoteling. This means that I no longer have a permanent desk to work at and I will need to reserve my desk for the days that I am in the office. This is where the Knack bag comes in. I am now having to carry a mobile office in my bag. Not only do I bring my laptop for work as well as a tech pouch for all the various dongles and power cords that laptop needs. I also bring my own keyboard and mouse. Since keyboards and a mouse get pretty gross anyway not to mention the risk of germs spreading, so having my own just makes things a lot more sanitary. The bag also holds my water bottle, my lunch and my shoes (I wear street shoes to and from work because the winter weather will ruin a pair of dress shoes quickly). The bag handles all of this without having to expand it. So if I need to bring a sweater or gym gear for after work I can just expand my bag and fit whatever else I need. In one bag! I see so many people ,especially women, carrying multiple bags into the office it is amazing that they don't have shoulder issues. I also really enjoy that I am hands free with the backpack because I can then open doors for others or pick up a coffee on the way in without dropping anything. With my Knack bag I know I have everything that I need for a successful day at work and with the professional look of the bag I don't feel like a school kid who walked into the wrong building. When I purchased this bag I had visions of traveling with it and it works really well for that but it has so much more versatility that just travel. I'm really happy with this bag and I'm so glad that I have it as my mobile office.
