HOW TO LIVE A ONE BAG LIFE - EVERY DAY

STAY CONNECTED

Use the Series 2’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.

SWITCH IT UP

Backpack, briefcase or tote? The choice is yours. When you want to change from a backpack, simply unclip the shoulder straps and tuck them away in the zip back panel pocket and voilà!

CARRY IT ALL

The spacious main compartment is a pocket-lover’s dream with two generously-sized, soft monofilament mesh organization pockets. If that’s not enough, there’s also a protective, fleece-lined tablet pocket and another pocket for your batteries/cables/chargers. Finally, the compartment's lockable zippers keeps everything secure.

ORGANIZE YOUR DAY

On-the-go all day? The easy-access front organization compartment helps keep you efficient and productive with its passport/wallet pocket, pen loops, business card pockets and handy removable interior key leash. And you can relax knowing that with lockable zippers and RFID-blocking lining to inhibit malicious RFID chip skimming everything stays safe and sound.

BRING YOUR SHADES

The fleece-lined, sunglasses pocket is designed for easy access and protection. And there’s a bonus pocket behind it for other items (phone anyone?) that you need at a minute’s notice.

DON’T LOOK LIKE A HIKER

Only you will know that the sleek, hidden, zip side water bottle pocket holds your 17 oz S'well™/ 21 oz Hydro Flask™ bottles/ 20 oz Knack Insulated bottle.

BE DISCREET

We’d love to tell you the location of the secret zip pocket for valuables, but then it wouldn’t be a secret.

HOW TO LIVE A ONE BAG LIFE - TRAVEL

EXPAND YOUR HORIZONS

Our patent-pending, hidden expansion compartment is the secret sauce that makes Series 2 the perfect One Bag Life backpack. Simply unzip and expand the compartment to get over 45% more carrying capacity. Unexpanded: 24 Liters. Expanded: 35 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: 11 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.

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 has a special antimicrobial treatment that helps to keep your Knack Pack fresh even when it’s filled with dirty or sweaty clothes.

Best backpack I've ever bought

I love this bag. The organizational capabilities of this bag are phenomenal, it has high quality materials, it fits under the plane seat even when completely filled, and has more space than I could have ever thought it would. I started to buy the large, but I'm happy I bought the medium because it was perfect for my trip. I do wish it came in brighter colors or at least more colors. The blue one was out of stock when I needed it so I got black, but would have preferred a different, brighter color.

Almost perfect

DESIGN and BUILD QUALITY
I must say that this is one of the nicer looking EDC/expandable bags around. It has great proportions, and it is sleek. The build quality is just as equally impressive, and I do feel like the construction choice will translate to a reliable backpack. I have done extensive research to finding a practical EDC and travel bag and this is the bag that I chose for numerous reasons. Firstly, it has the most pockets for accessories which is divided into two main compartments. Third zipper is the main compartment which can be further enlarged by undoing a well-hidden zipper; enhanced by an internal compression strap. The last zipper would then be your laptop compartment. This bag is also LIGHT-er! This is one of the lighter backpacks in its class. A lot of comparable backpacks are over 4lbs.

Though I am not too fond with the internal liner colour and design, I wish it was a little bit more… inconspicuous. The pattern just appears a bit too busy and a more solid colour or less contrast may be a welcome change. Also, this material is used all throughout the interior, and they are not stretchable. This makes it a little harder to be versatile in what you can put in them in the accessory pockets.
This backpack does check mark most of my needs but alas, there are certain improvements that can be (or rather should be) made to make this an even better product.

ENHANCEMENT RECOMMENDATIONS
- Dedicated discreet hidden mesh Airtag/tracker holder. A total must!
- Load-lifters. This is important considering that the bag can be expanded and become heavy. This would help the shoulders from some of the weight of the backpack by bringing the bag forward to bring the center of mass inward. Providing long term comfort especially for long-travel purposes. A must especially if this bag is designed to carry up to 40lbs!
- Detachable Waist belt. It seems odd that this was omitted from the Medium Knack backpack but can only be found on the Large version. It is a simple addition that even the medium backpack can utilize. Many similar sized backpacks from other brands have waist straps and I see no reason why the Medium should not offer it.
- The existing Knack logo on the shoulder strap should be a loop, allowing you to easily stow your sunglasses or attach a carabiner for other items (ie. Hand sanitizer). Making it a loop is an easy fix and can still add the logo on it. It becomes extremely practical and useful. A total must!
- Besides the loop where the logo is on the shoulder strap, perhaps a daisy chain may be added. Daisy chains are a number of webbing loops sewn in a linear series that are basically a whole bunch of lash points lined up. Useful for attaching small items.
- Luggage pass through improvements where they also place a strap that’s horizontal on the rear, allowing us the option to use either vertical or horizontal pass through. Personally, I would like a horizontal pass through so the bag can sit straight up and it is easy to access all items/pockets. The existing pass through is tolerable but it causes the water bottle side to face down and it no longer is accessible. Versatility is key and the simple addition of a strap should be added to give us options. A must!
- Water bottle storage is neat, but being hidden means that it takes internal space. It also is fully enclosed so any spills or moisture just pools inside this compartment and harder to clean. I feel like an expandable mesh that you can stow and unstow to allow the water to be outside the bag. Allows the use of more larger sized water bottles as well and easy clean up.
- Lockable laptop compartment and zipper flap. This seems like a large oversight. Only both accessory compartments are lockable. Also, this laptop zipper is missing a zipper flap… please fix this. Water could still get inside from this tiny access point because it’s not being protected by a zipper flap to redirect the water. A must fix on both fronts!
- Perhaps offering same product in different exterior material. A lot of brands are offering an alternative X-PAC fabric and the cool orange liner. Offering lighter weight and premium fabric durability.

These suggestions I think are important to consider. In fact, I would place some of them as a must if this bag is to be truly a backpack that meets most checkmarks. I hope they consider adding some of my suggestions, because I would re-purchase this bag and score it a perfect 5 in my books.

Perfect

From working as a traveling MA, to taking weekend trips across the country, to traveling overseas, to now medical school, this backpack has consistently been amazing. I have so many positive things to say, but to just pick a few, the expandable compartment is so useful when I need it and so easy to forget when I don't, the exterior and interior have held up far better than any backpack I've ever owned, and the layout of all the pockets is so well designed that I can't remember the last time I had to dig around looking for something at the bottom of the bag, especially with small things which fit perfectly into the many small pockets near the top of the compartments.

Overall, for anyone who can stomach the cost and finds themselves relatively on-the-go, I highly recommend giving this bag a try. I'm really glad I did.

Works great for Office & Travel

I had kept my Jansport Odyssey 37 for about 25 years and it finally gave out. I opted to go with this bag after an inordinate amount of research. Just got the bag a few weeks ago in blue and I love it. It's clean and fits in well in the office environment. It easily carries my laptop & charger, snacks, battery pack, insulated water bottle, and other accessories in the "day pack" mode. I really like that the water bottle hides into the bag - I was looking to ditch the external stretch pocket at this point. It holds a 20oz insulated Iron Flask narrow mouth with straw lid perfectly.
On the other hand, for travel, the bag easily expands and adds a ton of just bucket/luggage style storage. I'm able to carry: iPad pro 12.9", kindle, switch case, spare set of clothes, passport folder, over ear headphones, camera with extra lens, dopp kit, snacks, and probably some more things as I had extra space. Best part is when I get to my destination I can unload most of it, collapse the bag, and use it as a day bag.
Happy with my purchase.

Great bag. Shipping was. Or two day.

I LOOOOOVE this bag. So much. I used it for travel (which is why I bought it) and worked great. I am using it for work everyday now. It fit under the airplane seat, even expanded. However, I paid for two day shipping but it took four days. Also, the water bottle pocket holds a very small water bottle. I wanted to get the Knack water bottle but it was out of stock.

So glad to hear you are loving your Knack! In regards to transit time, this order was placed after noon EST on Friday, so it shipped on the following Monday with delivery on Wednesday. Thanks for the review and happy travels with your new Knack!

Best backpack I've ever bought

I love this bag. The organizational capabilities of this bag are phenomenal, it has high quality materials, it fits under the plane seat even when completely filled, and has more space than I could have ever thought it would. I started to buy the large, but I'm happy I bought the medium because it was perfect for my trip. I do wish it came in brighter colors or at least more colors. The blue one was out of stock when I needed it so I got black, but would have preferred a different, brighter color.
