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.

Almost perfect

Great bag and I’ve had many. Best bag for style, function, expandability etc. being a designer, this one always looks sleek and great even with a suit. My knack bag logo has popped off on 2 bags unfortunately, improvement needed there. Laptop zipper placement placement needs to be reversed to top of bag as laptop always sticks going in. Have to always manually move shoulder strap and really push zipper open. Not huge hassle but bothersome for quick in and out.
Weight is great. A bag is a bag, it’s only heavy based on what YOU put in it!

Finally found my forever bag

As anyone who knows me will tell you, I am OBSESSED with bags. For decades, I have looked high and low for that one bag that puts the search to rest. The Knack bag is that bag. It easily handles my everyday carry needs - and I carry a LOT. We're talking laptop, tablet, headphones, tons of chargers and cables and power supplies, personal items, keys, wallet, pens, notebooks and journals, and most days, a packed lunch and some snacks - and of course my Knack water bottle, which fits perfectly in the side pocket and doesn't hang out in some lame mesh pouch that makes me look like a hiker or a college student. The back is deceptively roomy while also being sleek and stylish enough to confidently carry into work meetings. There aren't dangly bits and a bunch of clutter, yet there is a pocket and place for everything you can imagine. AND THEN, as if this were not enough, there is the expansion that easily lets me pack for a long weekend trip. The packing cubes are like magic and allow me to maximize the space. Even loaded - and I just recently had this bag loaded and then some on a work trip, it was comfortable to carry, especially with the removable chest strap. I love that it slides on my suitcase handle, and even though it does so sideways, everything stays in place. The materials feels like high quality, the stitching is excellent, and it is a substantial, beautiful piece that never fails to get compliments. Oh, I went for the teal color, and it is really beautiful. It's bright without being obnoxious, and it gets compliments everywhere I go. This bag is one of the best investments you will make. Take it from someone who now owns two of these bags (I like having color options). If you are a commuter who carries a good of stuff, and you also want a bag that you can throw in 3 or maybe even four days' worth of clothing, Knack is the way to go.

Would be perfect if you could add a hip belt like the large version

I love this bag, but it gets too heavy when expanded and packed out for how thin the straps are. Would be the perfect all-in-one bag if they just made the medium version have a removable hip belt like the large.

Absolutely love this bag! It was a little pricey but it has held up very well so worth it. I use this bag every day for work at the hospital and then take it on trips with me. It still looks brand new and I’ve had no functional issues. It fits under the seat on delta flights so I’ve had no issues using it as a personal item. Would buy again!
