Knack Series 1 Laptop Backpack Fits up to 15 Inch - Knack Bags Carry-On Backpack, TSA Approved, Expandable Travel Backpacks With 3 Day Outfit Capacity (Indigo Blue, Medium)

I considered over a dozen backpacks, making a spreadsheet of comparisons of price, availability, features, dimensions, and more. After months of trial and error, I finally settled on the Knack Medium Expandable Backpack, and I couldn't be happier! It's comfort, has great interior space that EXPANDS, is built really well, and I love the color. It's a high quality backpack, and definitely worth the price. I strongly recommend this backpack!

I've had many backpacks over the years and this one is my favorite. Key things I really like:1. Expands so I can utilize the non-bulky slim mode for daily use and if I need to carry more things, increase the volume.2. Well made: sound quality and looks good3. Comes in colors other than black4. Well thought out design with easy access to pockets and numerous sections and pockets well suited for what they are to hold.

I returned this. But not because I didn’t like it. I actually loved it and had a lot of regret for returning it I think in the end I should’ve kept it. It’s really well designed, and the quality of the manufacturing is very good. It’s very clever the way they constructed the different spaces to keep things separate.. definitely recommend

I really wanted to give it a 5, but it’s a bit small and it doesn’t always stand up. It’s also a bit pricey. All that aside, the expandability is awesome, turning this rather small 17L daily commuter pack into a 27L weekend bag with a fully opening suitcase enclosure in the back. It has plenty of pockets and a very sleek design. It’s a 5 star bag + 3 star price = 4 stars

Great backpack with good organization. Can carry as an informal briefcase or backpack with hideaway straps or a shoulder bag. Good quality.Met all my criteria EXCEPT size. This is very small - probably only good for a day trip. I returned it and ordered the Medium from Knack website as the Series 2 was not available on Amazon

After my Coach tote finally wore out, I decided to make the switch to a backpack for work. I wanted a bag that could carry my stuff to the office and that I could also use for a quick overnight trip. My friend told me to check out Knack and after researching all their bags, I thought the Small Knack looked perfect (I am 5'4" and slight build). Unfortunately, when I got my new Knack, I was heartbroken when I didn't see any backpack straps. After poking around the bag, I'm embarrassed to say that I found the straps tucked away in a zipped closed back pocket ( I guess the straps can be tucked away so you can use as a briefcase?). Problem solved! I've since been using my new Knack everyday. The bag's organization, quality and capacity are great and it is just the right size for me. I am so happy with my decision!

This backpack was GREAT on my travels when I had to carry my laptop and camera equipment. The straps make it easy on my back when walking through airports. Also works nicely for weekend work trips, doing double duty as a laptop bag and suitcase. The materials are durable and easy to clean, and the zippers are good quality. A great purchase!

The media could not be loaded. I wasn’t sure what I was getting into but this backpack is definitely worth the investment. It’s extremely high quality and well designed. I love the quick access pockets in the front for things like my phone and AirPods when I’m on the go. I also love the expandable suitcase compartment in the back, which is perfect for travel and going from work to the gym. The material of the backpack is durable and the back padding is super comfortable to wear for long periods of time. There are also some fun features on the backpack that I have not seen before like the hidden water bottle compartment, the trolley sleeve, and the detachable straps that tuck into the backpack. 10/10 would recommend! My go to backpack for everyday now.
