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 13” laptops (measured diagonally) and its false 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 16 Liters.

DON’T LOOK LIKE A HIKER

Only you will know that the sleek, hidden, zip-away side water bottle pocket holds your 17oz S'well® or 18oz Hydro Flask® water 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 80% more carrying capacity. Unexpanded: 16 Liters. Expanded: 29 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: 13 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.

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.

Best bag for traveling

I really like this bag cause it has clever pockets and the expandable part is really useful. I have the small size and it is for small traveling with not more than 1 or 2 days of clothes... But it still got plenty of room and it looks cool. Nice build quality.

Love the bag so far for daily use!

So far I have only used the bag for daily use and work, but so far it has been great! I love having a specific spot for each item I carry around, and the bag has just that! It is made of really nice materials and seems very well constructed. I like that the straps can come undone and tucked in when I need to travel with it(though I haven't made use of that feature yet). The side laptop sleeve is a great idea, though it barely fits my 13" Lonovo Yoga 730 laptop, I'm glad I don't have anything bigger to put in it because it wouldn't fit. The laptop sleeve also is a little tough to get my iPad Pro in, but it is still functional. I do feel like the small zipper on the top could be a bit longer, and I feel like the angled zipper pocket on the front, though it looks unique, causes a lot of unusable space on the sides and above; there are blank cavities that I feel don't need to be there. I also wish the bag could stand up on its own, especially when I am out working at a coffee shop, and I can imagine at the airport.

Otherwise, I really love the bag. I'm excited for my upcoming work trip when I can expand it and put clothes and other items in the extra space.

All-in-all a great bag for what I do with it!

Love this Knack Pack!

Great versatile bag. Traveled with it on vacation, held the work and travel necessities in a small profile. Fit well under seats and in small overhead bins. Comfortable straps, easy access to all compartments with sturdy zippers and pulls. I haven't used the expandable section as expanded yet, but used it collapsed to hold papers, files, maps. Lightweight, yet durable. Only needs two upgrades: a couple of pen loops and optional hard sided insert for the compartment on the bottom of the bag (as in the eBags Professional Slim) to better hold cords and help it stand up on its own. I gave up mt eBags Professional slim for this bag--it's better quality and easier to access all the compartments.

Great Underseat bag

I was looking for a "personal item" bag to hold all my travel essentials. This definitely fit the bill! I can fit my iPad, phone, camera and all their cords plus a travel converter. Liquids, headphones, travel blanket and a couple of changes of clothes all fit in this great bag. I really like the thoughtful way the compartments were designed, with several pockets and nooks, and a large enough open space for clothes. Great!

Best Bag Ever!

Ok, so, first of all I returned the small for a medium as it was a little too small for someone 5 11. However that didn’t stop me from recognizing that it’s exactly what I was looking for (after many, many other bags I’ve tried).
As a day to day, it’s perfect. As a travel bag and day to day where you are going, it’s perfect!
From work to vacation, it’s perfect!
If you’re thinking of buying a Knack, don’t hesitate, just buy one.
And enjoy!
Thank you, Knack!

Small Knack

Decided to get the Small for my EDC bag and I love it. My little laptop for daily use fits comfortably and I can take my planner and books to class quite easily. It's also great for weekend trips and perfect for carrying your wallet and essentials while taking in the travel life. Love it and looking forward to a Spring color in small!

Best Backpack EDC and Travel

I bought the small Knackpack, I was not disappointed. It has replaced several other bags I owned as my EDC bag (I'm donating them to Goodwill). It's light, durable, and has awesome organization. The straps are comfortable and the bag fits well. I don't like backpacks that ride low on your back, I like my backpack to fit a little higher on my back and the small Knackpack fits just right. The expanded suitcase compartment is unbelievable, I have two short overnight trips coming up and can't wait to see how well the suitcase compartment performs. This is an excellent purchase for me and I plan on getting two more. Medium sangria red for me and small sangria red for my girlfriend. Thank you knack for a excellent product.
