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.

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.

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.

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.

PRODUCT REVIEWS

Over a year later: Best piece of gear I ever owned

I've been holding back on a review to test this one properly, but after about 18 months I can conclusively say - this is the best backpack I ever owned, and in terms of frequency of use - probably the best piece of gear of any kind I've bought, ever. In these 18 months, I've used my medium-sized Knack Series 1 to..

- Carry my laptop + my gym gear (shoes and a change of clothes) + books on gym days. Sleek and comfortable and looks better than most backpacks.
- Carry my laptop, several books, a smoothie bottle, the Knack water bottle AND 60m of climbing rope AND harness AND shoes, AND goggles AND swimsuit on climbing + swimming days
- Travel to Iceland, Africa, Middle East, and the West Coast - on trips ranging from 4 days to two weeks - always using the Knack as my only bag, carrying everything I needed for hiking AND working AND formal occasions.
- Everyday use, from meetings to shopping - obviously.

Only quibbles:
- The little pockets in the front compartment are quite unnecessary - who would put their credit cards there?
- Would be great to be able to purchase a detachable waist belt as well as a chest strap - when overloaded to the max, the pack does tend to chafe on the lower back.
- A rain cover would do wonders too, although so far the bag has been pretty elements-proof.
- And last but not least - PLEASE start delivering to Europe! The bag is the envy of half my UK friends and they'd be lining up to buy it if it sold here.

Great bag

I am a student and have loved using this bag. I bike everywhere and that includes the grocery store. Being able to go directly from classes to the store, expand my backpack to fit all of my groceries, and continue on with my day has been a considerable time saver and incredibly convenient. I will never buy a daily backpack that doesn't expand now and I plan to stay with Knack!

Perfect carry on

I purchased this backpack to take on my trip to Ireland. Great compartments for chargers, toiletries, medicines. Love that the large compartment unzips like a suitcase so that you don’t have to dig for what you are looking for. Very pleased with everything! My new go-to backpack!

Easy to order and received the product quickly.

I used my Knackbag on a trip through Asia. It was the perfect size to carry additional items that could not fit in my carry-on. I highly recommend this product!

Excellent

Exactly what I was looking for. Not too large but still fits everything needed. Excellent design.
