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.

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.

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.

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.

Makes an excellent bike commuter bag!

A little background: I probably own close to a dozen backpacks of all makes and sizes. The brands I own range from Camelbak to GoRuck. You can say I'm very fickle when it comes to backpacks.

This one has been in constant use since I got it back in July. I purposely waited a few months to allow time to really evaluate this bag and give my honest impressions. I've been using it as my bike commuter bag for work which is about 16 miles round trip. I use this bag while bike commuting about 3 times a week and use it when I'm commuting by car.

I am amazed at how comfortable this pack is on my back loaded with my work essentials and bike EDC. I keep a pair of chinos in the unexpanded compartment that I change into when I arrive at work. I love that I can keep a few items and pants in the luggage compartment without having to expand it.

To be honest, I wasn't in love with the triangular shaped admin pocket but I have adapted and love it for one reason. I can clip a round blinking amber bike light at the apex of the flap. Then I can tuck it in such a way that about 30% of the light is under the flap that houses the zippers when fully closed. The resulting tension holds the bike light in place quite securely when the flap is closed all the way with the zippers under the flap. I can even squeeze on the KK logo to press the power button to turn on my light! (I wish I could post a pic of what I am talking about!!! It's one of those things that just works out amazingly!) It means I can use my rear bike safety light without having a molle loop or any kind of loop for that matter.

Some additional points:

I ordered a factory 2nd example and for the life of me, I cannot find anything wrong with it!

The bag is deceptively small but it's really not. I love the sleekness of it as well as it's simple yet clever and innovative design. It offers so many carry solutions for my items without being overly complicated (like some tactical style packs).

It's light weight (especially compared to a GR1) but feels stout and ready for heavy loads (which it is). Even fully loaded with a laptop AND an ebike battery in the main compartment, the pack is still comfortable.

On the surface the bag looks simple yet is as comfortable if not more than some packs that "look" comfortable (a bunch of adjustment straps).

My only honest and hopefully constructive criticisms are as follows:

I feel like the number of business card pockets in the admin section is excessive. That being said, I've used some of this pockets for holding single Fig Bars or Clif Bars. It would be nice to see a pen sleeve or 2. Maybe even a pocket for a small flashlight. I would also like to see the key keeper relocated to the admin section.

For me, the key keeper in the main compartment gets in the way of the zipper pull of the internal mesh pocket on the back panel. Because of this, I keep that mesh pocket open mostly.

I would like to see maybe some gussets for the mesh pockets to give them more usable volume especially when the pack is full.

Lastly, I wish Knack went with a regular side release buckle on the sternum strap. My muscle memory keeps wanting to squeeze a buckle rather than clumsily trying to unhook it from the webbing. When in a hurry I feel like a side release buckle is just easier and faster.

All in all, I still give this pack 5 stars. I love it that much. The simple looks of it are deceiving. This pack is bigger than it is and more comfortable than it looks. It's a refreshing option for those looking for their next backpack. Well done Knackbags!

Great bag!

I have had the medium bag now for about a month and I love it. I park and commute daily to work. The bag is comfortable to wear daily and just the right size. I am able to fit my lunch box in the main compartment and use the expandable section if I have something else to carry in. This makes it very nice as I can make my trek each day and not have to carry anything. The quality of the fabric is excellent and the zippers are heavy duty. The blue color is very nice. I highly recommend this bag! I waited and purchased mine through the "seconds" sale for the savings. I couldn't find a thing wrong. Great product Knack!

Easy to Organize for Travel

I've used the medium for two trips and it has proven amazing for organizing all my carry-on items. Love the bottom pocket for my electronics/cords. I've only had to expand for one of my trips, but I see it being a huge benefit for my weekend trips and if I make purchases for my longer trips that go beyond the weight I can put in a checked bag. A friend I stayed with on my last trip ended up purchasing a Knack medium backpack based on seeing my usage.

2nd Knack Bag

I was so blown away traveling with my knack bag 1.0 that when the opportunity presented itself for me to purchase a 2nd. I jumped right on it. I travel alot with my company and was tire of paying luggage fees at the airport for a 2 to 3 day business trip. My knack bag simplified everything for me.

Very nice quality

I was waiting for these to go on sale to pick one up but when I seen the "seconds" sale, I had to try it. I was a little worried but I couldn't go wrong for about $60 off. When I got it, I looked all over for the "mistake" but I couldn't find it. This bag looks top notch all the way. I cannot wait until I go to Japan in March to test this bag out. Thank you for making such a nice quality bag.

Love my Knack Pack

I searched for months for the right backpack. Everything was either too large, too floppy or did not have well thought out pockets and design. Then I discovered Knack Packs. It was almost like love at first sight. The website was thorough. But I balked at the price. Then I received an email about a sale of "factory seconds" and the opportunity presented itself to get a Knack I could afford. I ordered the medium. Once it arrived, I spent time admiring all the features. It's is laid out very well. Everything has a purpose and function. It's well-built, and without expanding the pack, it will hold everything for the conferences I attend. When I want to add a jacket or more book, or even sandals, I can expand it to hold what I need. What more can I say - now it is love at first sight.

Clean Look. Great Bag!

I got medium black. Clean Look on the outside. Smart structure, Good quality. Feels light. I like that I can use the back luggage compartment's top open to push stuff in without opening it fully, like for gym cloths, etc...
I love the front compartment, how it opens and the see-through pockets. It's great for the day to day stuff. The front V style zipper is cool looking from outside :) though I personally find I never really use it.

My Biggest Complaint.. I don't like the expansion zipper. It feels cheaper and is super hard to open. Good thing i don't do that every day.

My second complaint, The luggage slide on in medium version is vertical and not horizontal, and it's super hard to push it in. I don't get why the horizontal opening does not exist in medium but does in the large version...

Needed organization & comfort

I researched a lot of bags. I do a lot of traveling and needed something that was functional, weather friendly, carry a lot of different things, and was comfortable- along with being day-to-day friendly when I wasn't traveling. I used to have a coach back pack - and I liked it. My Knack bag is SO MUCH more user friendly and functional. Going back and forth to my office (especially if I have to run and catch a boat nor train), is super easy now - and the bag has a nice classic look.

My Knack bag does it ALL!! It has been a grand slam!
