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.

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!

Needed to organize

I really needed to have an organized carry on and this is it!!! This backpack was easily organized for a portable office at my destination and for what I wanted on during travel: airport/plane. I love it!! I could not believe how easily it fit under the seat. Thank you Knack!

Great for weekends!

This bag is awesome! It works really well for weekend one-bag travel. Everything I need fits and I can carry it on the plane.

Made me a believer #onebaglife

I LOVE Knack Packs...#onebaglife was a mystery to me. How in the world could one bag could be so versatile? The more I travel with my Knack Pack, the more I appreciate its design, functionality, and durability. Recently my neighbor was looking to consolidate his work and travel bag for a trip and in letting him borrow my Knack Pack - he too is now a HUGE fan and ordered one upon his return as it helped him do more than consolidate his array of gear, it helped him stay organized as it does me on my trips. Ease of use, sleek design features that more than live up to their expectations for functionality, and very light on its own given the material (tough and rugged to say the least), Knack Pack have more than exceeded my expectations to convert to #onebaglife. Lastly, a pleasant surprise with the interior lining of Knack Pack being orange/white mix, it brightens the space within the bag (especially on the airplane) to find what I need to use quickly. It's the best travel bag I've ever used and now own. Knack Pack is the only travel bag I use now moving forward. Kudos to the team who brought this to market! Thank you! Bring more! :-)

AWESOME BAG

I love this bag. It’s very well designed and durable. It’s built for everything. 10/10 recommend. I’ll never use another bag again.

nice bag

First Knack Bag Purchase

I love my new Knack bag! I recently took it on a trip to Arizona and it was perfect. I really enjoy having different pockets on this bag to store everything I need. Great quality and worth the money.
