If you in need for a backpack and you researching for the perfect backpack, this is the one. This backpack is a little bit pricey but is well worth it in my opinion. I been trying to research on the best backpack since it's so many options to choose from, and I bought 5 at a time so I can choose the best one and this is by far the best traveling bag, and the best selling point is it can extend to a bigger size, if you're trying to research on the perfect bag, I've done the homework for you, this the backpack you want, and it's well built, premium.

Top quality all around. Storage areas make sense and are able to make access easier. Exactly what I was looking for. Packed enough for 3 day trip.

Great backpack, fits my 15in laptop just fine. The flap in the expandable section is super weird though, that area could be better designed.

Researched and decided knack was the one and it is a great solution for my needs! Great quality and love the expandable compartment!Update after a few months...... This pack is perfect for what I wanted! It is designed well and works perfect for a daily carry for me as well as a single bag for overnights. Storage is well thought out!

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

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'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.

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!
