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 17” laptops (measured diagonally) and its false 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 22 Liters.

DON’T LOOK LIKE A HIKER

Only you will know that the sleek, hidden, zip-away side water bottle pocket holds your 25oz S'well® or 24oz 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 over 70% more carrying capacity. Unexpanded: 22 Liters. Expanded: 37 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: 15 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.

Bag It Knack It

I love my bag. I bought it for a short business trip to keep things simple, but I didn't know how much I could carry in it; I had two days of clothes, a laptop, a camera, and some accessories. It is amazing. Now I'm planning to take road trips, long weekends and I can wait to pack my stuff in my Knack bag.

I cant say enough things about this bag and the company it represents.

Not only is this bag incredibly functional and sleek, but the team also have the best customer service.

I needed this bag quick as I was heading out of town for a very important business meeting. The problem is I purchased this bag around an holiday weekend.

Nevertheless, the customer service team pulled a few extra strings and ensured I got my bag within a business day.

And this bag truly is "sleek and sexy professionalism meets extreme functionality".

Only my highest recommendations!

The bag you did not know you could not live without. Clearly the  of Bags

Short version: Order a KnackPack now and thank me later. 
Long version: I studied backpacks for six weeks before buying one. I am an avid RedOxx bag owner. I own six bags of theirs. I could not get over their backpack looking more a hiker than a minister and missionary.

I found Knack through reviews. I bought the large. I could not believe the quality or the spaciousness of the bag. 

I put it through a 12 day trip only carrying my tech. I loved it. I did not unzip the expansion section. It was perfect for plane and car and coffee shop travel. I came home; I did two, two-night trips with my suit packed. The suit did not wrinkle. It fit the overhead bin even with the expansion pack unzipped on a 900.

Great customer service by Rachel. I had two minor cosmetic concerns. She responded with grace and exceeded expectations. 

I wholeheartedly endorse this bag.

Well designed!

This Knack Pack is well put together. Everything has a place and kept very neat. At the airport two people asked me about it. I saw one other Knack Pack and it looked good .

Great bag

I thought the large size would be too big but it's actually very comfortable and fits everything

Almost perfect. Negligible downsides.

Expectations are the same as reality! The pockets and organization do their job well. It IS VERY sleek when in compressed form. The large one looks very good on a 5' 11" person, even on someone a bit shorter than that. The material is great, the look is great, the top handle is great, the capacity is great.

The triangular front pocket is a bit awkward, but still functional. The sternum strap cannot be removed, and you can end up with a lot of dangling stuff.

This bag is fantastic!

I am a flight nurse in the Air Force and take frequent overnight trips... prior to this bag, I had two choices: 1. mix clothing and equipment in one large compartment, or take two small bags; however, thanks to the Large Expandable Knack Pack I can pack a change of clothes... a spare flight suit... and all the paperwork/equipment I need to complete my mission. This is the best "flight bag" I have used!

Very happy with this bag overall as a daily carry and travel bag.

I have been extremely happy with the purchase of this bag. Love how the main and front triangle compartments fold open, giving a good visual of the contents without spilling anything. It has the feel of handing you it's contents which combined with the smooth zippers that can be used with one hand, I can get what I need blindfolded. The amount of space is perfect for my daily carry where there is just enough space for an extra sweater or jacket. The expansion gives exactly enough space for my 2 packing cubes and toiletries. I do wish the bottom compartment was big enough for a pair of shoes. I don't want to put my laptop cable there as that is a 3rd zipper then to get my laptop setup but it's too small for anything beyond a pair of flip flops.

Comfortable but the back panel gets sweaty on my bike rides to the office. The off center hip belt is also kind of annoying and just barely tightens enough for my 30" waist. Also the chest strap needs an elastic to hold the excess strap so it's not bouncing around while walking. Shoulder straps are great. The clips that hold them on are really nice and can be used to hold excess strap.

Overall I really like the look. The grey was a bit darker than expected but I like even more than the pictures. It just looks good sitting there in my room. It would be nice if it stood up on it's own but it's solid enough to lean against things really well.

Great bag few improvements needed

This is one of the best backpacks I ever owned. The size of it is great and space is amazing. Few recommended things to perfect it:

- the zippers get stuck sometimes
- the back memory foam is great but gives you a sweaty back after a while of carrying.
- the front pocket with 2 zippers could have better organization as the current form limits what could be placed.

I know knack will get it fixed and my only regret is that I will have to purchase and pay for the newer version at some point.
