When we started Knack, we focused on creating backpacks that freed people from carrying multiple bags at the same time. Since our launch, we’ve heard from hundreds of people who love our concept of One Bag Life™ and who also give us great feedback on how we are doing. Their honest comments help us to continue creating game-changing products and customer service. Because we find reviews from Knackpackers to be so helpful, we thought we would share them with you as you think about whether One Bag Living is right for you.

The best bag I've ever owned!

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.

Best bag I’ve owned

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.

Found my favorite!

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!

Needed to organize

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!

Great for weekends!

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.

Made me a believer #onebaglife

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.

Andrew Bushnell (Sunnyvale, US)
nice bag

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

First Knack Bag Purchase

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.

Great backpack for a graduate

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

All in one - One for all.

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!!!

The perfect work and travel bag

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.

quality product - just not the right fit

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.

The Bag that every Teacher or Coach should get!

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.

Superb Build, Very Well Thought Out

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.

Best Bag Period

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

Great Bag for travel and School

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!

Love this bag!

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.

Hah!! This pack is GREAT!

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!
