I have had the Medium backpack for almost 2 years and it is still like new! I use this bag daily and it carries so much! I can carry my laptop, iPad, 2 large notebooks, planner and so much more! My large water bottle fits great in the side pocket. This is the only backpack I've found that actually keeps my items super organized and easy to access.
I've also used this backpack for weekend trips and I've been able to pack everything I need for the whole weekend in this one bag! I can't say enough great things about my Knack backpack!

Stylish, comfortable and tons of pockets/storage!

I did a lot of research even though little travel is done these days. My "only" and recent trip ended up with canceled flights after canceled flights (three in a row) and this bag really made it almost bearable! Kudos Knack!

I have been using this bag for a couple of weeks while traveling and the bag is excellent. The customer service is amazing too, they helped me solve a very specific issue.

I chose the Olive version, which does not include leather, which to me was preferable. It looks great, a professional look, with very good materials. The expansion to me worked very well, and I didn't find any other option that would go from 27L to 35L (other options were mostly too small).

The way I use it is mainly on plane travel, when I have a sling for quick access everything (and use it at my destination), a small rolling suitcase and the Knack Bag over it. Then when I need to board, I expand the Knack Bag and put the sling into the expansion, so I only have two pieces of luggage. Worked perfectly! Great product, can't recommend it enough.

I have purchased numerous other backpacks (according to the hubby - too many) and none of them have worked for me like this one has! Took it on vacation which was what it's initial use was for, but it has continued to be my daily bag. Fits everything I need/want to carry on a regular basis - books, clothes, etc. - in a very organized way. Well worth the purchase! Now what to do with the others .....

I have always been picky about my backpacks, as I have needed a spectrum of multi-day backpacking packs to small bags. I use my new Knack Pack for the daily grad school grind and occasional weekend travel. I needed a bag that could hold multiple pairs of clothes, laptop and/or tablet, my lunch (which, admittedly, some sizes of Tupperware don’t comfortably fit in the Knack Pack), and a bunch of odds and ends of various sizes, such as chargers and measuring devices for school. I walk to/from campus everyday, the straps are very comfortable, even when I (rarely) have to bring home textbooks. This bag is a dream to travel with- it is seriously awesome to have such a streamline, efficient, and well throughout bag with me. I also have to comment on how well made the Knack Pack is, the zippers are study, the material seems robust, and there are no plastic parts! I think I will be able to use my Knack Pack for many years, and will be able to adapt the bag to my needs as they change over time.

Note: if you frequent need to carry heavy, oddly shaped, or bulky objects then other backpacks would be a better fit.

After spending the last 4 years trying over 30 different backpacks, I finally found the one that I believe is absolutely perfect. The knack bag series 2 is absolutely perfect for both an everyday carry as well as a travel backpack. I don’t think I have even seen such a well designed backpack. Everything from the antimicrobial lining to the well organised and spacious compartments makes this the ideal backpack.

It can easily expand to a travel backpack that can carry a week’s worth of clothing if you pack it neatly. Yet, at the same time it collapses into a slim form factor for when you want to use it as an everyday carry.

The excellent build quality of the backpack also makes it extremely durable and great for travel, while the sleek design makes it equally well suited for the office.

I absolutely love this backpack and can’t wait till series 2 large backpacks come out so I can get my hands on one of those.

I've been keeping my eye on this bag for a while. Watching reviews and researching other bags. It was out of stock for a while and finally it came back in stock. I jumped on ordering it. I love it so far. I use it for work every day now. I originally wanted it for travel, so I can't speak of that yet until borders open up. But it is everything I needed and exceeded expectations for back and forth to work. Thank you Knack!

I’m very glad I finally made the call to spend some money and treat a great backpack like an investment.

The quality and build is top tier, and there are a ton of storage options built in for organization but at the same time this isn’t overdone. One of my biggest pet peeves with “fancy” backpacks is when it’s designed for EVERYTHING to have a space so as soon as you have something that doesn’t fit the pre planned layout your bag is now much less useful. Knacks avoid this pitfall with grace!

If you’re on the fence and know you need a bag that can do it all, go ahead and get it. You’ll be impressed and satisfied.

I shopped around a lot looking for a single bag that did double duty for short work trips. I landed on Knack because I liked the mix of features and space for work stuff and clothes/toiletries, etc. Having taken the bag on a couple trips I couldn't be happier with my choice. It's clear that the bag was designed by people who sweated the details. Loads of little pockets and zippered storage areas. Like that there's room for 6 pens (always a pet peeve that there aren't enough in most bags). I used one of the backpack zipper pouches for my toiletries - maybe not how it was designed, but I like that there's enough space to be creative with packing. I actually have a 17 inch laptop that doesn't fit in the sleeve, but slots nicely into the large backpack compartment. Then I use the laptop sleeve for notepads and folders. Very well made as well. If you're looking for a "one bag life," at least for overnight trips, you will not be disappointed.
