I love this bag for more than just travel!
My company has implemented a flexible work schedule which means I am in the office a few days a week and home for the rest. However along with the flexible work they have also added desk sharing called hoteling. This means that I no longer have a permanent desk to work at and I will need to reserve my desk for the days that I am in the office. This is where the Knack bag comes in. I am now having to carry a mobile office in my bag. Not only do I bring my laptop for work as well as a tech pouch for all the various dongles and power cords that laptop needs. I also bring my own keyboard and mouse. Since keyboards and a mouse get pretty gross anyway not to mention the risk of germs spreading, so having my own just makes things a lot more sanitary. The bag also holds my water bottle, my lunch and my shoes (I wear street shoes to and from work because the winter weather will ruin a pair of dress shoes quickly). The bag handles all of this without having to expand it. So if I need to bring a sweater or gym gear for after work I can just expand my bag and fit whatever else I need. In one bag! I see so many people ,especially women, carrying multiple bags into the office it is amazing that they don't have shoulder issues. I also really enjoy that I am hands free with the backpack because I can then open doors for others or pick up a coffee on the way in without dropping anything. With my Knack bag I know I have everything that I need for a successful day at work and with the professional look of the bag I don't feel like a school kid who walked into the wrong building. When I purchased this bag I had visions of traveling with it and it works really well for that but it has so much more versatility that just travel. I'm really happy with this bag and I'm so glad that I have it as my mobile office.

I travel a lot and being able to keep all of my work stuff in a nice organized place is extremely beneficial. Love all of the different areas for organization!…but wait there’s more! This bag turns into a full suitcase for short term trips, for easy packing and simple travel!! They gave you everything with this bag. Quality, comfort, organization, style. Well done Knack

I already own 3-4 different bags to be ready for any kind of trip (i.e. commuter, daypack, weekend/duffel and a 'going abroad' bag) and my knack bag solves everything. I've been looking for a backpack slim enough for a day trip but expandable enough in case my trip takes longer and I want to take home additional stuff. Best purchase ever!

I'm 65 years young and was looking for a backpack that I could take on a weekend trip but would expand into something larger for longer trips but still be considered carry on luggage without checking at the airport. I recently retired and planning on global travels to complete my bucket list I've been building up.I did a lot of research and watch a ton of Youtube videos getting all the information I needed to make the decision that was right for me. I needed something that was on the light side yet sturdy enough to hold everything without sagging and losing shape. The Knack fit everything I was looking for. It has a sleek design without all the "in your face" branding. Some reviewers stated they wished the shoulder straps had more padding but I find them adequate for me since I'm not a nomadic blogger/youtuber so I don't carry a lot of heavy equipment. The shoulder straps are a nice size to hold my GoPro clip and comfortable enough to get me through the airports, trains and short walks through the new destinations. I like they can be zipped away and you can put items in there as well.

Now the inside. I really like the zip up water bottle compartment on the outside. I use it for not only my water bottle but a selfie-stick or collapsible walking sticks depending on the trip I take. The front(first) area has a lot of smaller "stick-in" pockets. For me it's an over kill. I wished there were fewer zip up see through mesh pockets here. I don't need 3 pens. I use the elastic loops for charging cables, chapstick or anything for quick access. The space at the bottom is large enough to house my travel journal, headphones, and GoPro carrying cases. The second zip up area holds a ton. I use this area for my iPad, toiletries bag, other charging cable, puff jacket, rain gear if needed. Really anything I might want quicker access without opening up the main compartment. I think the best feature of this bag is the clamshell opening. For shot trips it holds everything in place. But when I want to go on longer trips, it expands and I can fit two medium compression cubes easily with room to spare to pack along the sides for an extra pair of shoes.

These types of backpack are very subjective and everyone has their needs on what they want to carry and expectations. But this one hit almost every mark for me. Safe travels everyone!

Best all in one bag you can possibly find. Amazing quality and every inch is utilized

I took a recent trip and it held my 17" laptop easily and a weeks plus worth of clothes. That was without expanding it.

I bought this as a gift for my daughter on her HS graduation, she is loving the backpack that she’ll be using as a college freshman in the Fall of 2021

The video reviews of this back DO NOT DO IT JUSTICE!!!
I bought this bag for my wife to use for work; Real Estate. She texts me almost daily (for the last week) RAVING about this backpack. As a family who hikes, this back is almost perfect for taking to the trail! Plenty of storage, slim, lumbar support is 5 of 5!!!
THIS BAG IS AWESOME!

Good quality backpack with a nice look. I was able to put 3 polos in the large cube, 3 tshirts in the medium cube and sleepwear in another medium cube along with 2 pairs of pants and a sweatpants with more room to spare. Worth the price I paid.

I heard back from Knack regarding my return. So I have changed my rating to a 5 star. They did recognize my concern and fix it for me.

The bag was great, but I felt my MacBook Pro did not fit well in the side pocket. It was a little tight and difficult to remove.

The Large was just too big, but I may change my mind at some point. I still am on a quest to find the perfect bag for me.
