See What Knackpackers Are Saying

On The Subway and On A Plane

I had specific needs when I was shopping for a new backpack: since I'd be carrying it to the office and on business trips, I didn't want it to look like I was heading out on a campaign trip. I wanted it to have enough space to carry my gym clothes or one change of clothes and toiletries for an international flight. I wanted to be able to easily reach small objects without having to completely remove the whole pack and put it down somewhere. I wanted it to be able to easily carry a water bottle securely. And as a short woman (5'0"), I wanted the bag to sit comfortably on my hips.
This bag hits all those marks and then some! In addition: the space for storing cords and chargers is a thing I didn't know I was looking for. The small top pocket for storing sunglasses is also perfect for storing my my ear buds.

Actually As Good As They Say

I'm almost 2 years into my knack pack journey. After extensive research, I reluctantly purchased this bag for work travel. 30-40 trips a year. This bag needed to hold 2/3 days' worth as well as all my work gear and supplies. Not only does it still look brand new, I have never needed anything on the road as it has a place for everything. It's so good, I use 2 compression cubes and have ditched my suitcase altogether. You'll never need another bag.

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.

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

LOOK SHARP

Inspired by tailored clothing fabrics, Knack’s custom-designed, two-tone fabric is both lightweight and durable.

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 15.6” 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.

It’s good

On the subway and on a plane

I had specific needs when I was shopping for a new backpack: since I'd be carrying it to the office and on business trips, I didn't want it to look like I was heading out on a campaign trip. I wanted it to have enough space to carry my gym clothes or one change of clothes and toiletries for an international flight. I wanted to be able to easily reach small objects without having to completely remove the whole pack and put it down somewhere. I wanted it to be able to easily carry a water bottle securely. And as a short woman (5'0"), I wanted the bag to sit comfortably on my hips.

This bag hits all those marks and then some! In addition: the space for storing cords and chargers is a thing I didn't know I was looking for. The small top pocket for storing sunglasses is also perfect for storing my my ear buds.

My one small request for improvement: when I travel and go to the toilet in bathrooms in airports in a variety of countries, the carry handle on top isn't well situated for hanging the bag on a bag hook in a toilet cubicle. Since we use the bottom of the bag for the cord storage, I'd rather not be putting it down on strange bathroom floors. Just a suggestion to keep in mind for future design! :-D

Expectations Far Exceeded!

I have become obsessed with my Knackpack Series 1!!! And NO, this is not a paid review. I saw an Instagram ad for this Knackpack when I was in the market 6 months ago for a laptop backpack that would hold my personal Macbook + work laptop + coffee tumbler + a few personal effects, without looking too bulky or masculine (I have a small frame at 5' and 100 lbs). Price was not too much of an issue, but I wanted to stay under $500, so TUMI was out of the question. I took a chance and ordered the Series 1 in Medium (black), cautious that I may have to exchange for a size up bec in the website photos, it looks a bit small... I didn't want to get the Series 2 bec I like all the pockets and organization far more in the Series 1, and Series 2 looked a lot bigger (vertically) in the photos. Do NOT let the size of the Series 1 Medium fool you. I have been absolutely blown away at the quality of this company!! Not only was the packaging so carefully thought of, it arrived quickly, and for a backpack that looks so small, it fits soooo much and never ever looks bulky. When traveling, it slides very easily under the seat in front of you. Oftentimes, I grab the essentials from my purse or tote and toss them in my Knackpack to be completely hands-free. One thing I really appreciate (besides all the pockets and org) is that the pocket for the tumbler is hidden away. I HATE those backpacks that expose the water bottle or tumbler and it's just floppin around as you're frantically running to catch a connecting flight lol. I'm a forever customer as long the quality remains this way!!

Note to the company: You guys are doing some really great work - thank you for this gem. :)
