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.

I thought about this purchase for quite a while. I have now had it for a little over a month and had the chance to go on a work trip with it. I chose this pack because of its more professional look but with the versatility of having room for travel. The expandable feature is amazing and lives up to my expectations. The zippers and material are great quality and I expect to hold up well. I also like the lighter color interior, it makes it so much easier to find things. I was surprised at how much of a difference this made. I have a large and thick 15.6 laptop and have had issues finding packs of this size that would fit my computer and I am happy to report that this one does, though you probably couldnt fit a laptop too much bigger than mine. I want to note a few things about the design. I use the pack in its condensed form for day to day use. I wish that the main pocket had a little bit more "give" or width to it. I like to carry my lunch with me and it is a pretty tight squeeze to fit tupperware into this pocket simply because there isnt much width to the pocket, although it is very deep. On this note, if you have all of the pockets in use it can fill up this main compartment pretty quickly. In future versions, I think it would be nice to have a "tech" pocket inside the laptop compartment, so my laptop accessories could be together. But, these are small things and I am really glad I made this purchase and am excited to use this for years to come!

It took me over a year to finally pull the trigger and buy this backpack. I’m glad I waited because I was originally going to get the series 1 but after the series 2 came out I’m glad I waited. The materials used on the backpack are high quality including the zippers. I love the design too. There are so many pockets and flaps to keep all of your stuff organized. I love how the main compartment opens up fully. It allows you to get to all your clothes easily without messing up your fold jobs on the clothes you haven’t used yet. I only have one design issue and it’s not even really an issue just a preference. I could do without the expandable aspect of the backpack. Every time I use the backpack I am using it with the main (expandable) compartment open. It functions fine and everything but the extra zipper there can make it confusing to find the zipper that actually opens the compartment. That is my only observation that isn’t completely positive and I’m sure a lot of people appreciate that the bag can be slimmed down when not using the big compartment but for me I just never need it slimmed down. This bag is totally worth the price.

I've been using my small Series 1, V2 Knack bag for a while and whilst I love it there were a couple of niggles (mainly the bottom pocket which I never really found a good use for and the opening of the front pocket which I always felt was a bit too vulnerable to pickpockets).
The Series 2 is a great upgrade. The larger size doesn't affect the comfort of the bag, which was my main concern sizing up and the extra capacity is welcome ..... or will be, when I can travel again. By far the biggest plus to the S2 Knack is the new front pocket which replaces the bottom, top and admin pockets on the Small V2 ..... I find the pocket layout better suits the items I need to carry and it feels a little less vulnerable to even when a lock isn't used. I also like that the zippered pocket inside the luggage compartment has more dimension to it, handy for packing smaller items of clothing. Lastly, the new fabric isn't a magnet for my dog's hair :)

I have a series 1 and a series 2 and I’m a big fan, I use them for different things and each has advantages. Best backpacks I have ever used.

Great for the fire service. Some days I need to just carry my MacBook and gym clothes, next day I need all that plus a full set of office clothes. It converts between so easily. Strong work knack. On the next gen. add another small D hook at the top and throw in a shoulder strap. Easy addition with minimal work. Thanks
