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.

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.

Nice Expandable size that hit almost every mark for me

I'm 65 years young and was looking for a backpack that I could take on a weekend trip but would expand into something larger for longer trips but still be considered carry on luggage without checking at the airport. I recently retired and planning on global travels to complete my bucket list I've been building up.I did a lot of research and watch a ton of Youtube videos getting all the information I needed to make the decision that was right for me. I needed something that was on the light side yet sturdy enough to hold everything without sagging and losing shape. The Knack fit everything I was looking for. It has a sleek design without all the "in your face" branding. Some reviewers stated they wished the shoulder straps had more padding but I find them adequate for me since I'm not a nomadic blogger/youtuber so I don't carry a lot of heavy equipment. The shoulder straps are a nice size to hold my GoPro clip and comfortable enough to get me through the airports, trains and short walks through the new destinations. I like they can be zipped away and you can put items in there as well.

Now the inside. I really like the zip up water bottle compartment on the outside. I use it for not only my water bottle but a selfie-stick or collapsible walking sticks depending on the trip I take. The front(first) area has a lot of smaller "stick-in" pockets. For me it's an over kill. I wished there were fewer zip up see through mesh pockets here. I don't need 3 pens. I use the elastic loops for charging cables, chapstick or anything for quick access. The space at the bottom is large enough to house my travel journal, headphones, and GoPro carrying cases. The second zip up area holds a ton. I use this area for my iPad, toiletries bag, other charging cable, puff jacket, rain gear if needed. Really anything I might want quicker access without opening up the main compartment. I think the best feature of this bag is the clamshell opening. For shot trips it holds everything in place. But when I want to go on longer trips, it expands and I can fit two medium compression cubes easily with room to spare to pack along the sides for an extra pair of shoes.

These types of backpack are very subjective and everyone has their needs on what they want to carry and expectations. But this one hit almost every mark for me. Safe travels everyone!

Best bag I’ve ever seen and bought

Best all in one bag you can possibly find. Amazing quality and every inch is utilized

Perfect travel bag

I took a recent trip and it held my 17" laptop easily and a weeks plus worth of clothes. That was without expanding it.

Great backpack for a graduate

I bought this as a gift for my daughter on her HS graduation, she is loving the backpack that she’ll be using as a college freshman in the Fall of 2021

The video reviews of this back DO NOT DO IT JUSTICE!!!
I bought this bag for my wife to use for work; Real Estate. She texts me almost daily (for the last week) RAVING about this backpack. As a family who hikes, this back is almost perfect for taking to the trail! Plenty of storage, slim, lumbar support is 5 of 5!!!
THIS BAG IS AWESOME!

The perfect work and travel bag

Good quality backpack with a nice look. I was able to put 3 polos in the large cube, 3 tshirts in the medium cube and sleepwear in another medium cube along with 2 pairs of pants and a sweatpants with more room to spare. Worth the price I paid.

quality product - just not the right fit

I heard back from Knack regarding my return. So I have changed my rating to a 5 star. They did recognize my concern and fix it for me.

The bag was great, but I felt my MacBook Pro did not fit well in the side pocket. It was a little tight and difficult to remove.

The Large was just too big, but I may change my mind at some point. I still am on a quest to find the perfect bag for me.

Coach Anthony Stone (Rockford, US)
The Bag that every Teacher or Coach should get!

Knack Packs are the most versatile bags on the market. I can go straight from teaching school to the airport and have all of my electronic devices to teach and clothes for a weekend business trip in one convenient bag. I speak from experience since I travel a lot running football camps all over the world, the Knack Packs are high quality and hold up extremely well.

Superb Build, Very Well Thought Out

I wouldn't call myself a backpack aficionado but I do have a lot that I seem collect and use for a variety of purposes. I was pleasantly surprised at how much I like this bag. It is now my favorite for work and travel. I have the medium and it is deceptively roomy. I often carry two laptops and this bag seems to gobble them up and still has plenty of room for power adapters, files, other cables, and notebook. that's without even expanding the clothing compartment. It has enough compartments for your various essentials but not too many where you don't know where anything is. Well done Knack.

Best Bag Period

I have had lots of backpacks. Ones designed for skateboarding and snowboarding. Ones designed with travel in mind. Many for every day use. The Knack out performs them all. Not only is it great for weekend getaways. It performs as an everyday bag with ease. It keeps everything safe and secure with more features than you knew existed. #onebaglife
