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 15” 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.

DON’T LOOK LIKE A HIKER

Only you will know that the sleek, hidden, zip-away side water bottle pocket holds your 17 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 40% more carrying capacity. Unexpanded: 27 Liters. Expanded: 39 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: 12 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.

Did SO much research and this is the best backpack I've ever had

I spent forever searching for the perfect backpack and even bought and tried several before finding Knack. Honestly this bag is perfect and I couldn't be more happy!! 10/10 recommend.

R
Rochelle Combe (Avalon, US)

This is a great travel bag. I go back and forth between 2 homes every 2 weeks and this is perfect. I always have my 2 dogs with me so having hands free is necessary. I can pack a weekend's worth of clothes plus my essentials (laptop, phone, sunglasses, tickets etc.). The only thing I wish it had was a bigger pocket for a water bottle (it fits a 500ml bottle), but I haven't really found another bag that does either so I think it's pretty standard. Otherwise the bag is perfect. Great quality, nice looking and keeps me organized.

Great bag

First trip, this bag was great. Plenty of storage pockets. This is a great 1 to 2 day carry on bag. Love the expandable option.

The best backpack I have owned

As an airline pilot, I've worked through many bags from rollers, to messengers, to backpacks. After buying and returning multiple bags, I bought this one and it has been my daily work bag that I can carry everything needed for my flight, to include snacks, books, ipads, and a change of clothes. The rugged construction has made it through almost a year of flying around the world, multiple luggage compartments, cockpit, hotel stays, airports, taxis etc. It is very comfortable to carry. Only wish would have been that the Knack logo was embroidered, as the little rubber lettering peeled off while in the confines of the cockpit.

Great bag

I now travel with one bag. This is a great bag with lots of compartments for organization. I can go 4-5 days with just this bag. I highly recommend knack!

Awesome bag

Had the opportunity to travel this weekend with one bag. Awesome piece, highly recommend it. Very well thought out design, sits nicely on your back to distribute the load. Just excellent.

Great Bag

I have been traveling with two bags for business for over 10 years. What a joy to leave one bag at home and have enough room for clothes and business necessities. Bravo!

The best bag I've ever owned!

I work remotely most of the time and travel a lot both for work and pleasure, often alternating between an office bag, a day bag, and a suitcase. Inevitably, I'd leave things I needed in another bag and it was a huge hassle. When I saw this bag on Instagram, I compared it to all the other "all-in-one" bags on the market I could find, but nothing impressed me as much as Knack. I've been using my medium Series 1 Knack Bag for a few weeks now and I'm dazzled by how comfortable it is, how much it packs into a tight space, and how much it holds both daily and when expanded for my trips! I love this backpack so much that I've already listed my other three bags for sale after just a few weeks of using this. Also, the compression cubes made for this bag are AWESOME! I easily fit 3-4 days' worth of clothes and necessities in them for camping, "unpacked" my clothes, and zipped up the luggage area in less than 30 seconds to hit the beach. BEST BAG EVER.

Best bag I’ve owned

I’ve owned quite a few backpacks and THIS bag is by FAR the best bag for my computer And travel.. to marry a computer & carry-on bag with a durability and convenience of a hiking bag is genius.. well done.

Found my favorite!

I am really happy with my Medium Series 1 in Sangria Red. The bag is spacious, excellent quality, perfect for my commute to the office. I originally purchased the smaller version but it turned out to be too small for my needs, although I loved the size. The return process was easy and quick. I was on the fence about purchasing this brand but I am glad that I gave them a try. Knack Pack is my favorite!
