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.

Knack Packs are the most versatile bags on the market. I can go straight from teaching school to the airport and have all of my electronic devices to teach and clothes for a weekend business trip in one convenient bag. I speak from experience since I travel a lot running football camps all over the world, the Knack Packs are high quality and hold up extremely well.

I wouldn't call myself a backpack aficionado but I do have a lot that I seem collect and use for a variety of purposes. I was pleasantly surprised at how much I like this bag. It is now my favorite for work and travel. I have the medium and it is deceptively roomy. I often carry two laptops and this bag seems to gobble them up and still has plenty of room for power adapters, files, other cables, and notebook. that's without even expanding the clothing compartment. It has enough compartments for your various essentials but not too many where you don't know where anything is. Well done Knack.

I have had lots of backpacks. Ones designed for skateboarding and snowboarding. Ones designed with travel in mind. Many for every day use. The Knack out performs them all. Not only is it great for weekend getaways. It performs as an everyday bag with ease. It keeps everything safe and secure with more features than you knew existed. #onebaglife

I got this bag based on a suggestion from a memeber of a Stage lighting group. I was looking for a bag that could hold my large laptop and its peripherals, a change of clothes, and tools or my school books or whatever miscellaneous things I might need. The backpack succeeds in doing all that. Ive used it as a suitcase/travel bag for when I went on a short vacation, I've used it to hold my computer and desk stuff as I was moving into my apartment, and I've used it as I've gone too and from classes. It work great in all those applications and the straps are nicely padded so there was no strain on my shoulders.
My only issue is there are not as many pockets as I would like and the main pocket is just a tiny bit smaller than I would like (still fit my roughly 18" laptop). However, I was able to remedy these issues by using the suitcase pocket in the back.
Overall it is a great multipurpose backpack!

This is my second Knack bag. My first was extensively used during a family vacation across Europe last summer. My wife and kids loved the bag so much I decided to get another in a different color/size for myself. The pouch at the bottom is great for cables and charging cords. Love the water bottle pocket as well, it works for so many things. A quality bag. Worth every penny.

I got this Knackpack when I started my MBA at the Wharton School. I didn't realize what a cool pack it was until I started using it. After a year of traveling across the country for work and class, it still looks brand new. It has been rained on, thrown under airline seats, and stepped on in the classroom. I literally carry it every day, but you'd never know. It holds its form well, protects all my stuff, and has the perfect amount of space to pack for a workday (when not expanded) or a three or four day weekend (when expanded). The backpack that is changing the backpack. Great job, Knackpack!

I work remotely most of the time and travel a lot both for work and pleasure, often alternating between an office bag, a day bag, and a suitcase. Inevitably, I'd leave things I needed in another bag and it was a huge hassle. When I saw this bag on Instagram, I compared it to all the other "all-in-one" bags on the market I could find, but nothing impressed me as much as Knack. I've been using my medium Series 1 Knack Bag for a few weeks now and I'm dazzled by how comfortable it is, how much it packs into a tight space, and how much it holds both daily and when expanded for my trips! I love this backpack so much that I've already listed my other three bags for sale after just a few weeks of using this. Also, the compression cubes made for this bag are AWESOME! I easily fit 3-4 days' worth of clothes and necessities in them for camping, "unpacked" my clothes, and zipped up the luggage area in less than 30 seconds to hit the beach. BEST BAG EVER.

I’ve owned quite a few backpacks and THIS bag is by FAR the best bag for my computer And travel.. to marry a computer & carry-on bag with a durability and convenience of a hiking bag is genius.. well done.

I am really happy with my Medium Series 1 in Sangria Red. The bag is spacious, excellent quality, perfect for my commute to the office. I originally purchased the smaller version but it turned out to be too small for my needs, although I loved the size. The return process was easy and quick. I was on the fence about purchasing this brand but I am glad that I gave them a try. Knack Pack is my favorite!

I really needed to have an organized carry on and this is it!!! This backpack was easily organized for a portable office at my destination and for what I wanted on during travel: airport/plane. I love it!! I could not believe how easily it fit under the seat. Thank you Knack!

This bag is awesome! It works really well for weekend one-bag travel. Everything I need fits and I can carry it on the plane.

I LOVE Knack Packs...#onebaglife was a mystery to me. How in the world could one bag could be so versatile? The more I travel with my Knack Pack, the more I appreciate its design, functionality, and durability. Recently my neighbor was looking to consolidate his work and travel bag for a trip and in letting him borrow my Knack Pack - he too is now a HUGE fan and ordered one upon his return as it helped him do more than consolidate his array of gear, it helped him stay organized as it does me on my trips. Ease of use, sleek design features that more than live up to their expectations for functionality, and very light on its own given the material (tough and rugged to say the least), Knack Pack have more than exceeded my expectations to convert to #onebaglife. Lastly, a pleasant surprise with the interior lining of Knack Pack being orange/white mix, it brightens the space within the bag (especially on the airplane) to find what I need to use quickly. It's the best travel bag I've ever used and now own. Knack Pack is the only travel bag I use now moving forward. Kudos to the team who brought this to market! Thank you! Bring more! :-)

I love this bag. It’s very well designed and durable. It’s built for everything. 10/10 recommend. I’ll never use another bag again.

really enjoy these bags, have a series 1 and a series 2. clearly a lot of thought went into the design. there are some features on the series 1 i like better and some on the series 2 i like better, but these come down to personal preference

I love my new Knack bag! I recently took it on a trip to Arizona and it was perfect. I really enjoy having different pockets on this bag to store everything I need. Great quality and worth the money.

Love this backpack!

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.

I love the bag. I was cramped in my prior bag, and the Knack has plenty of room for all my work and personal every day items. Well designed, looks great, beautiful materials. Love the contrasting lining that lets you see everything in your bag and the expandability for files or a set of clothes for travel.

My only gripe is that while the bag arrives with mostly paper packaging, it also has a plastic film bag and some styrofoam. Knack, please work on 100% really recyclable or compostable packaging!

I’m proud that you’re a Rhode Island company!

I purchased the small backpack to use in addition to my small roller bag that I use for travel. The backpack is perfect! The backpack saved my shoulders from having to carry a clumsy and heavy tote bag. I was able to fit just as much into my small backpack as I was into a small roller bag. It also fits beautifully underneath the seat on the airplane, while providing easy access to what I needed on the flight from the top zipper pockets. I absolutely love it and found it incredibly comfortable to carry (wear) while rolling a bag and carrying a coffee. Perfect solution to my painful totes. Thank you Knack for the well thought out design.

This bag literally saved my life when I was hit by a car in New York City on 12/12/2020. The amount of stuff I was able to have in my bag helped it have the weight for me to stay on top of the vehicle instead of going under and when I was launched from the cars hood it broke my fall and I didn't get any upper body or head injuries. Without this bag I would have probably went under the car and be dead.

I got my small black knack pack a couple of weeks ago...it is just what I was looking for. I researched for several months and almost purchased a few others but glad I waited. I got the black because I prefer simple and stylish and it's the most versatile...can go from travel to the office. I got the small because the recommended size for most under seat sections of aircraft, especially smaller airlines, say up to 17". I was concerned it would be too small but it really holds all of my daily carry stuff well (I have a lot of stuff as it's my "go bag" as well) and will fit two packing cubes (one large/one small) no problem which should carry enough clothes for wherever I go. I love the idea of just adding my clothes and going wherever knowing I will still have all of my "stuff" with me. The laptop sleeve is tight...I have to take off my mouse USB insert and work it in slowly but it fits so that works for me. I have a 13" Lenovo Yoga L390. So far it's holding up beautifully to all of the daily use. It's very comfortable as well.

I bought a Medium previously and love it. However, I found that I could use something smaller for a weekend trip or for general daily use unexpanded. The Small really fit the bill. It’s great for a short trip, especially if you pack strategically with compression packing cubes.

All the features of the Medium or Large in a more compact package. My only complaints are the lack of a side carry handle (see previous Medium review) and in the Small’s case, the fact that the water bottle holder is undersized. I realize it may be impractical for a bag this size, but I prefer carrying a 24 ounce water bottle. However, I can fit my virtually indestructible and leakproof water bottle in the interior of the pack.

Great product and quick shipping. Really like this company!

I looked at this bag for months before buying it. I had never spent this much on a bag of any sort, so I was a bit hesitant to spend so much on a backpack. And I wasn't even necessarily looking for a backpack, but let me tell you, this bag exceed expectations in every way. The ability for this pack to expand was a bonus to me, and it truly is incredible. I mostly love how when the bag is collapsed in its smallest form that its ability to expands is totally hidden from view. You cannot even see the zippers. This bag is really convenient & surprisingly spacious. The thought & design put into this is worth the price alone, but the quality makes it a no-brainer. If I had seen & interacted with this bag in person, I would have bought it on the spot & not waited for months. I love the little touches that are brilliant design, like being able to hide a water bottle & the location of the laptop sleeve. I am really glad that I got this size bag for a daily commute & I look forward to traveling with it. I probably won't even need a suitcase for short trips! Literally the only thing I miss in this bag is a slot to hold a pen, but the mesh pockets inside suffice. This bag is a high-quality & well designed piece of gear & it's a lot nicer than the average backpack. I highly recommend it!

If you are anything like me, the price was a bit of a turn off. Well I bit the bullet and bought one and AM NOT DISAPPOINTED! Best bag I have ever bought! Excited to see how it holds up!

Purchased for my wife, after having one myself. Perfect size, she loves the color too!

So roomy, pockets for everything, and gorgeous.

I really like this bag cause it has clever pockets and the expandable part is really useful. I have the small size and it is for small traveling with not more than 1 or 2 days of clothes... But it still got plenty of room and it looks cool. Nice build quality.

I was skeptical, but, as advertised, I've managed to pack for 2-day weekend trips even in the winter where the thin shirts are replaced with fleece quarter-zips. And while it looks bulky when filled, it's still comfortable to wear and walk around with.

My only issue is that the leather is so nice and soft, I'm worried about taking it on work trips (construction sites) or checking it on a plane (if needed). I may need to get a second pack for such trips and save this one for weekend adventures.

Wonderful backpack , very classy with adequate compartments. Great finish. Would highly recommend everyone getting one !

This is my second medium Knack, but my first
made of leather. The leather is definitely worth the additional money. I love my first bag, but this one takes it to a whole new level. Same functionality as all the other Knacks, but the tactile qualities really communicate the capability and luxury of the leather option. Sleek and strong...it doesn't get any better than this.

Great design as a work bag and the convenience to pack for an overnight trip changed the way I travel!

Took my new Knack Backpack on its first trip and love it! Great leather that looks slick. Compartments are super practical and shoulder straps are comfortable. Found nothing to improve so far...
