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

I'm been searching a couple of years for the perfect work bag for 1-3 day bus travel, around the house, working from the side of a soccer field, or going into the office. This bag nails it perfectly. It can be a bit heavy if fully loaded do to my stuff, but I carry up to a 14" laptop, 2nd display, 30mAH battery bank, earbuds, over ear headphones, range of cables/adapters, and a full keyboard (for the really remote working). It fits everything in an organized fashion. Expand it out an it's an easy 1-3+night road trip. Most of the time I don't carry all the stuff and it's a compact, lightweight, functional backpack around town.

I have no problem using this with casual/formal business meetings. If the backpack is the wrong look…I have a fancy messenger bag that's now collecting dust.

I've stopped searching for bags now.

I have what could be called a "bag problem." I'm always on the lookout for the perfect bag and have bought many that are close but not quite there. Then I bought the Knack 2, and it is wonderful! It satisfies my need for lots of pockets for organization and the ability to go from every day use to travel easily. It has room for everything! Best bag ever!

I have the Series 2 in grey, and I'm in the middle of my third, 1- to 2-night trip with it as the sole bag. I love the clean, contemporary design and material quality; plenty of well-organized room for everything I need -- including two laptops (one 15", one 13") in the sleeve. Even when travelling with a suitcase, this bag is and will be my carry-on / underseat bag of choice.

The Series 2 Knack Pack delivers on every level. It's good looking and highly functional. My son loves it and has already put it to good use.

So glad to have found the Knack Pack. It's a perfect fit for my adult son's busy work and outdoor activities. Just the kind of gift he will use and appreciate.
