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.

Best bag I’ve ever seen and bought

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

Daniel Gurecky (Port Charlotte, US)
Perfect travel bag

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

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

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.

Coach Anthony Stone (Rockford, US)
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!
