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 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 15 Liters.

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® or 18 oz 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 80% more carrying capacity. Unexpanded: 15 Liters. Expanded: 27 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.

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 end of lugging heavy totes!

I purchased the small backpack to use in addition to my small roller bag that I use for travel. The backpack is perfect! The backpack saved my shoulders from having to carry a clumsy and heavy tote bag. I was able to fit just as much into my small backpack as I was into a small roller bag. It also fits beautifully underneath the seat on the airplane, while providing easy access to what I needed on the flight from the top zipper pockets. I absolutely love it and found it incredibly comfortable to carry (wear) while rolling a bag and carrying a coffee. Perfect solution to my painful totes. Thank you Knack for the well thought out design.

This bag saved my life

This bag literally saved my life when I was hit by a car in New York City on 12/12/2020. The amount of stuff I was able to have in my bag helped it have the weight for me to stay on top of the vehicle instead of going under and when I was launched from the cars hood it broke my fall and I didn't get any upper body or head injuries. Without this bag I would have probably went under the car and be dead.

perfect for me

I got my small black knack pack a couple of weeks ago...it is just what I was looking for. I researched for several months and almost purchased a few others but glad I waited. I got the black because I prefer simple and stylish and it's the most versatile...can go from travel to the office. I got the small because the recommended size for most under seat sections of aircraft, especially smaller airlines, say up to 17". I was concerned it would be too small but it really holds all of my daily carry stuff well (I have a lot of stuff as it's my "go bag" as well) and will fit two packing cubes (one large/one small) no problem which should carry enough clothes for wherever I go. I love the idea of just adding my clothes and going wherever knowing I will still have all of my "stuff" with me. The laptop sleeve is tight...I have to take off my mouse USB insert and work it in slowly but it fits so that works for me. I have a 13" Lenovo Yoga L390. So far it's holding up beautifully to all of the daily use. It's very comfortable as well.

Great smaller complement to the Medium

I bought a Medium previously and love it. However, I found that I could use something smaller for a weekend trip or for general daily use unexpanded. The Small really fit the bill. It’s great for a short trip, especially if you pack strategically with compression packing cubes.

All the features of the Medium or Large in a more compact package. My only complaints are the lack of a side carry handle (see previous Medium review) and in the Small’s case, the fact that the water bottle holder is undersized. I realize it may be impractical for a bag this size, but I prefer carrying a 24 ounce water bottle. However, I can fit my virtually indestructible and leakproof water bottle in the interior of the pack.

Great product and quick shipping. Really like this company!

Fabulous bag

I looked at this bag for months before buying it. I had never spent this much on a bag of any sort, so I was a bit hesitant to spend so much on a backpack. And I wasn't even necessarily looking for a backpack, but let me tell you, this bag exceed expectations in every way. The ability for this pack to expand was a bonus to me, and it truly is incredible. I mostly love how when the bag is collapsed in its smallest form that its ability to expands is totally hidden from view. You cannot even see the zippers. This bag is really convenient & surprisingly spacious. The thought & design put into this is worth the price alone, but the quality makes it a no-brainer. If I had seen & interacted with this bag in person, I would have bought it on the spot & not waited for months. I love the little touches that are brilliant design, like being able to hide a water bottle & the location of the laptop sleeve. I am really glad that I got this size bag for a daily commute & I look forward to traveling with it. I probably won't even need a suitcase for short trips! Literally the only thing I miss in this bag is a slot to hold a pen, but the mesh pockets inside suffice. This bag is a high-quality & well designed piece of gear & it's a lot nicer than the average backpack. I highly recommend it!

Literally the BEST bag I have ever bought.

If you are anything like me, the price was a bit of a turn off. Well I bit the bullet and bought one and AM NOT DISAPPOINTED! Best bag I have ever bought! Excited to see how it holds up!

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!
